After a brief wait for delivery, I received the new Handheld Blue Laser in the mail. It was well packaged and the handheld laser was in a sturdy vinyl box. The box was covered in very nice leather-looking vinyl and containing a cut foam insert. However, the insert was cut for the body of the laser pointer without the battery cover attached. So, to store the handheld laser, you must remove the battery cover. Overall, this is not a critical issue, and removing the batteries from the Red Laser Pointer during storage is probably a good idea anyway. It requires a small amount of time to put the unit together before use and that could be an issue in low light levels. The case is large enough to hold the handheld laser with the battery cover attached and batteries inside, but the foam would need to be cut in the case to allow the handheld laser to be stored in one piece. Also included with the handheld laser was a lanyard with two keys to unlock the laser body, and a 3.5 mm tip sleeve plug that can be wired into a system that will allow remote operation of the laser. This PowerPoint presenter has a green laser pointer and a radio frequency USB receiver with built-in 8GB memory. Simply connect the receiver to the USB port of your computer and you can forward and backward slides by pressing the next and back buttons on the laser pointer. You can also save and get files from the receiver with 8GB memory. It uses built-in rechargeable Lithium battery, Supports PC and Mac. Comes with USB cable and luxurious gift box.
Laser light from laser pointers can potentially burn the retina of the human eye. The danger is obviously greatest if the beam is aimed directly into the eye, rather than merely scattered from the beam and seen from the side. The danger is dependent on the wavelength of the laser light, the power of the laser pointer, the divergence of the laser beam, the distance of the person from the pointer, whether the beam is seen directly or via a reflection, how long the beam is viewed and whether the human eye's natural 'blink response' to bright light occurs.The risk from a laser pointer is often also expressed by the 'class' of the laser pointer, although the definition is a little complicated and class definitions have changed in recent years. At one end of the scale, Class 1 laser pointers are safe for normal viewing. Eye damage from directly viewing the beam of a Class 2 laser pointer is usually avoided by the blink response. Class 3 laser pointers can damage an eye before it has time to blink and have the potential to cause eye injury, especially in the hands of a careless or untrained operator. Class 4 Astronomy laser pointer are even more dangerous, higher power devices.All of this stuff is housed in a sturdy pen-sized housing that holds everything in place and protects the innards from the weather and the operator. Don't try to take the pointer apart as this will void the warranty, as will removing the serial number sticker. Battery life depends on usage, but 2-3 hours of on-time during busy operation can be expected from two AA alkaline cells. Cold temeratures reduce the performance of the laser and batteries, so keep the pointer warm at the chilly star parties. The life of the Sony IR laser diode is about 4,000 hours, or something like 1,600 sets of batteries. The rest of the components will operate unless they are subjected to significant impact. Treat your laser pointer like you treat your eyepieces and it will last a lifetime. The final product of all this technology is a vividly bright green beam! At night, the beam appears to go all the way to the stars. When pointing out a faint fuzzy, folks within several yards of the pointer will clearly see the beam and the place you are pointing.
The handheld laser came with the laser body and battery end cap. Batteries were not provided so I immediately ordered two sets of UltraFire 16340 1200mAh 3.6V Lithium Ion batteries. While they were on order, I decided to buy a couple of Duracell 123 non-rechargeable lithium batteries to try it out. The 123 batteries were rated at 3V, but showed 3.2V when placed into service. Initial inspection of the handheld laser body indicated that it was made of aluminum and anodized in black coating. It is slightly more than 23mm (0.9”) in diameter, 184mm (7.25”) long, and weighs 172g (6.1 oz) with batteries installed. Although not heavy, this handheld laser has enough heft to keep you aware of what pocket you are keeping it in. The body of the laser has several labels containing information and warnings. The largest label on the body is placed right above the pressure activated one click on, one click off button. This label warns that this laser is intended for laser professionals and those over the age of 18 years old. It also clearly states the duty cycle of this laser at 5 to 10 min. of use, with at least a 1 min. rest period. The label also has an OSHA danger placard warning of direct exposure to the laser beam, and it stated wavelength range of 405 to 450 nm. A label below the locking system shows compliance with the FDA, RoHS, and CE Conformity. A white label right above the removable battery cap is printed with the model number and serial number for the handheld laser. Green Laser Pointer produce a beam of light that is coherent, monochromatic, and unidirectional, and can converge most of its radiant power over small areas, even at great distances. Laser pointers are useful ubiquitous devices used in everyday situations, especially in the educational environment. They are also used frequently by children as toys. Their potential to cause retinal damage is a matter of concern, and manufacturers warn against injudicious ocular exposure to laser light. Low-energy green laser pointers are generally considered to be safe devices and their potential to cause retinal damage is questionable. Here we report a case of macular damage caused by a green laser pointer in a teenager, along with a brief review of the literature.
The blink response should protect the human eye at any distance from any visible-light laser pointer beam with a power under 1 mW, typical of a Class 2 laser pointer. For laser pointers that are more powerful a greater distance is required to allow for blink response protection. For a given laser pointer beam, a quantity called the Nominal Ocular Hazard Distance (NOHD) can be calculated. Serious eye damage is probable within the NOHD and less likely at greater distances. The NOHD depends on the power, wavelength, divergence and diameter of the beam and the length of time the laser pointer beam will be viewed. For example, a 10 mW, collimated, continuous wave, green (532 nm) laser pointer beam with a diameter of 1 mm and divergence of 10-3 radian, being viewed directly for 10 seconds has a NOHD of 55 m. Clearly, this laser pointer, typical of many green laser pointers, is a potential hazard to someone close to it and should be used with care.Laser pointer devices are a common and essential part of everyday life. This may lead to an increasing number of exposures to this type of Blue Laser Pointer device. However, there is debate about the ocular risks posed by inadvertent exposure to standard laser pointer devices, with the presence of an actual laser-induced injury often inconclusive or entirely absent in some studies.1–3 Literature supporting laser pointer-induced retinal injury has been limited to only a few articles on class 3A red laser pointers, and even less literature exists on the retinal hazards of class 3A green laser pointers. In the literature, retinal lesions induced by laser pointers (both green and red devices) include foveal granularity, perifoveal drusenoid-like deposits, or foveal ring-shaped hypopigmented lesions, subretinal hemorrhage, vitreous or chorioretinal hemorrhage, retinal edema, scars in the pigment epithelium, and rarely choroidal neovascularization.
We performed quantitative measurements, showing that the weak unit emitted approximately 10 times more invisible IR light than the visible green. Green light activates the eye's blink reflex, which provides a protective mechanism. However, we are completely vulnerable to IR radiation, since exposure to it may only be noticed after significant retinal damage has occurred. After further investigation, we found that this problem is common in low-cost GLPs, although its seriousness varies widely. We propose a simple diagnostic method to detect IR radiation that requires only access to a common Web camera.Inexpensive GLP operation is based on three key elements, each of which marks a milestone in the history of laser technology. First, a semiconductor 808nm-wavelength diode laser pumps a neodymium-ion oscillator, which produces radiation at 1064nm.High powered green laser pointer’s light beams and dots are many times brighter than other laser pointers and are much more soothing to the eye. This makes them much more visible. In fact, you can see the actual high intensity laser beam, not just the small dot because of the power of green laser beams. When it is important that the laser dot is visible regardless of lighting a Laser Gloves is by far the best choice, and are surprisingly cheap. This is the reason why today’s astronomers, military personal, serious business professionals and educators use high powered green laser pens.Mini handheld green laser pointer pens come for sale in a variety of different power watts. The class ii or 1mw green laser pointer pens and class 3A 5mw green laser pointers are the safest to use. It is actually against US regulations to use green laser pointers that have high power laser beams over 5mw in public environment. Anything more powerful than class ii 1mw or 3A 5mw is not necessary for presentations or even armature astronomy. The laser beam and dots of class ii 1mw and 5mw green laser pointers are extremely powerful and visible in dark or light condition.
A recent addition to the backyard astronomer's laser pointer 100mw
Toolkit has been flagged as a potential weapon in the terrorist's arsenal. The humble laser pointer, used by thousands of skygazers to show beginners the way to stars and constellations, is coming under fire from U.S. federal and state authorities following thousands of incidents in which laser beams have "painted" aircraft in flight.In the most notorious case, on January 4, 2005, New Jersey stargazer David Banach was charged with interfering with the operation of a passenger aircraft and lying to federal investigators. He'd been arrested the preceding week after allegedly shining a green laser at a private jet on approach to a nearby airport and then at a police helicopter dispatched to search for the culprit. The green laser pointers in common use among astronomers and the general public have a power output of a little less than 5 milliwatts; in the U.S., these are called Class 3a lasers. Lower-wattage strong laser pointer , such as those in CD players and laser printers, are Class 1 or 2, while higher-wattage units, such as those in medical or industrial equipment, are Class 3b or 4. The higher the class, the more severe the warning label required by the US Food and Drug Administration (FDA).Compared with incandescent light bulbs, which draw tens to hundreds of watts (not milliwatts), 5 mW sounds like very little. But laser light is highly concentrated into a very narrow beam. Moreover, this beam is highly collimated, meaning it diverges (spreads out) very slowly. Laser pointers typically emit a beam about a millimeter in diameter. Even as far as a kilometer away, the beam is no more than a meter across. For stargazing applications, a 5-mW green laser is completely adequate.
There is a class of lasers, IIIa, which by law must be less than 5mW (of measured optical output, not electrical input). This class is legal to sell in the United States, and legal to operate outside in the United States (local or state exceptions may exist) provided you don't do anything stupid. Shining the laser at aircraft in flight, or moving cars, or other equally moronic acts can easily land you in prison for an extended time (and rightly so). Apparently a man who wanted to see if he could hit airplanes as they were landing was in fact successful. Thankfully, none of the pilots crashed, but the man was reported to have received a seven year prison sentence.The next higher class, IIIb ranges from 5 to 500 mW. You can also legally purchase this class of laser in the United States. But there are restrictions on it's use, because these lasers are capable of permanently damaging vision. You can't use it in an Laser Pointer where the beam could escape to the outside. To be explicit here, this means you can't legally use them outside. Now you may want to adopt a "no blood, no foul" attitude, and that's fine for you. But just know that if you ever make a mistake, or run into a narrow-minded individual, you don't have a legal leg to stand on - prepare for a good screwing. Furthermore, based on my own <5mW product, there is no reason outside of inferiority complex to get a higher power product for astronomical use.The first 10,000 feet gives us a laser beam across almost 90 degrees of our view. And the next 15,000 feet of beam visually lengthens the visible beam by a size smaller than the disk of Saturn, Jupiter, or Venus. In other words, while the beam is fading out gradually, the part of it that we can actually see, the close part goes almost all the way to where we're pointing, while the long long section that fades out, adds almost no visible length to the beam. Even the section of the beam starting after one thousand feet away only lengthens the visible beam by the size of a crater on the moon that's too small to see with the naked eye.
The Orion SkyLine Deluxe Green Laser Pointer is perfect for stargazers. It emits a thin but distinct green laser beam that appears to stretch all the way to the stars! SkyLine's < 5mW green beam just keeps going and going, seemingly to infinity. It works in light-polluted or moonlit skies just as well as crystal-clear skies in remote locations. It's great for pointing out stars, planets, constellations and more for others to see. The SkyLine Deluxe now uses electronic feedback regulation to ensure ultra-stable beam intensity compared to other green lasers on the market, even in cold temperatures.
The aluminum laser pointer body is 6" long and features a convenient pocket clip. Two AAA batteries are included.Lasers have many applications like astronomy and hunting. Expecially Green Astronomy Laser Pointer can be seen in usages such as astrophysical maser and atom laser. A low-powered Laser Rifle sight is used by astronomers to easily point out stars and constellations. You can find the best astronomy laser pointer in Lasereshop.com.Have you ever been outside under a clear starry sky with a friend or family member, when you wanted to point out the location of the Orion Nebula, or trace the outline of the Sagittarius "Teapot" asterism? You point your finger, but that just doesn't cut it. "Where are you pointing? Do you mean the third bright star up from that middle pine tree over there?" Save yourself from frustration and take the guesswork out of the equation with the Orion SkyLine Deluxe Green Laser Pointer. Its bright green beam makes pointing out objects in the sky as easy as pie.
Visit any star party and you are certain to see the same scene acted out many times. Someone extends his arm and points to an object in the sky. People next to him struggle to spot the object and repeatedly fail. The problem is that because they can't sight along the arm of the person doing the directing, they see it at an angle causing an angular distortion that is all but impossible to adjust for. The director points to one star and to the observer it look like he's pointing at a completely different spot in the sky. This is a phenomenon called parallax. Fortunately, around 2004 green laser pointers became available and solved this problem.Because the human eye is more sensitive to green than red light, there is enough light reflected off dust particles in air to make the beam from a green laser pointer visible at night.as the beam from a laser pointer 300mw travels through air.Since the beam is so much longer than an arm the problem of parallax isn't a problem.By 2008 prices for green laser pointers had dropped enough so that considerably more powerful units were practical. These are attractive because their beams are longer and easier to spot. The question I wanted answered was: "How powerful a laser do you need for astronomical pointing and how do different power levels compare in the field."Repeated Internet searches failed to turn up a single site that addressed these questions so I decided to investigate them myself. This page presents the results of my studies.
The FDA does offer advice to help consumers identify which Blue Laser Pointer products might
We have a big crow problem. They will sit, 20 at a time, in our trees and just squawk at each other all day long, often starting at 4:45 am. For the past 10 years I have tried to shoo them off with a pellet gun, which is mostly an exercise in frustration.I now have three lasers from Dragon Lasers, 15mw Viper, 90mw Spartan and 200mw Spartan. Totally works. Does it keep them away permanently? No. But it beats having to re-load a dumb pellet gun and wake up the neighbors. I've only found it to work on crows. Doesn't phase bluejays, which can be annoying, too.Another nice thing is that I can just wave the laser at a group of trees where I hear the yaking, without having to see the actual crow. the best laser pointers for peasants and farmers.Do you also suffer from birds to your yard or in the barn?

The greater a laser pointer's output power, the more likely it will cause serious eye injuries, burn skin and temporarily impair the vision of pilots or drivers. That much is clear.But judging the safety of that laser pointer in your desk drawer or in your kid's hand isn't simple."The consumer is in a difficult position," said Daniel Hewett, health promotion officer at the U.S. Food and Drug Administration's Center for Devices and Radiological Health, the agency tasked with enforcing the rule for products that emit radiation.As power increases above five milliwatts, the time margin for safe exposure decreases and permanent eye and skin damage can occur quickly. However, the output power of laser pointers is not immediately apparent to the user. Laser pointers often lack appropriate labeling or are mislabeled, and definitive testing of individual pointers is beyond the reach of the average consumer.The FDA does offer advice to help consumers identify which Blue Laser Pointer products might be dangerous and how to use devices safely. The agency is making laser safety awareness a priority just as a new study has shown that even the briefest exposure to high-powered blue handheld laser products can cause serious eye injuries.

This laser has become very common in the market in recent laser jaren.De yellow laser pen emits electromagnetic radiation (EMR) having a wavelength of 593.5 nanometers. This laser has become very common in the laser market in the last few years.The most yellow laser pointers are based on the DPSS (Diode Pump Solid-State) process with the aid of two lines of the radiant NdYV04 crystal (Neodymium Yttrium Vanadium Oxide) and a KTP crystal. The KTP crystals containing potassium, titanium and phosphorus. The DPSS controls infrared (IR) laser diode emits light at 808nm, which is fired in the rare element neodymium. The crystal processes the 808nm infrared light and transmits it at 1064 and 1342 nanometers, and then it will be fired in the NdYV04 and KTP-crystal and added with a non-linear crystal doubling with the light frequency of 593,5nm, resulting in the bright orange yellow tint and visible laser. This light beam is then filtered in order to remove the remaining infra-red light of the pump and the diode neodymium crystal. Finally, the light that is collimated or is focused by an optical lens to emerge as a very fine and exquisite laser.Due to the complexity of this process is to produce the yellow laser pointer expensive. This complex process requires precision engineering for temperature, stabilizers and active cooling technology.
There are several reasons for the construction of a burning laser in this manner, instead of only to be connected to batteries and having the die in a few days or months. The best reason is that it will just be a little more powerful. But the main reason for the construction of this circuit is to regulate voltage and current. As simple as connecting your diode is a set of AA batteries. You must realize that you are feeding the diode too much power. It is also not protected from other hazards, such as power surges. This driver circuit will ensure this.A laser pointer can flash a broken balloon. The light is so strong that within one beat burns a hole in the plastic. With your cornea is done exactly the same. And that is beyond repair. This past year, dozens of young people with such injuries to the Radboud Hospital in Nijmegen, told ophthalmologist John Keunen to the NIS.You can also buy the laser diode on green laser pointers or you can just pick your own from an old or broken DVD burner that you have laying around. And the question that asks you to answer yourself now, so it should be a DVD burner. Possible to 16x or higher speed. Normal DVD players diodes will not create a laser pointer with burning power. Never use a CD burner for this project not. They contain infrared diodes. The light they emit is invisible to the naked eye and have enough power to blind you before you even realize it's happening. Simply put, stay away from CD Burner diodes. You can not really see the laser will anyway make.Now, pick a laser light starry sky a tricky process because they tend to be very fragile and prone to static and other forms of shock. It is very important to take your time to harvest your precious diode. Do not ever fall!

Of course not, you will be able to touch the button green pen pointing to the sky, to your style surge. It can also be used for the disaster such as fire, flood, earthquake emergency site command.High powered laser are classified as "Class IIIb 'lasers. High power lasers are also used recently emerge in the consumer market in specialized military applications, which leads optics / physics research laboratory and all over the world.Green laser ?? are known for their green small beam diameter and high power. To the human eye, with its inherent sensitivity to the color green, the green laser pointer provide powerful and bright green color pointer and be seen everywhere. Carry with them an intense burning power so great in the fact that they burn through many fusible and combustible objects.Promotes: Green laser can be seen traveling tens, even hundreds of miles in the dark. With exceptional power, high intensity energy beam and extended laser pointer 300mw , create? They run a pheromone only seen in sci-fi movies.In the public sector, and almost all research stations these very intense and visible green bars are convenient, especially for astronomers studying Celestial objects such as stars, for the beam often seems to reach out to the object.Laser Afficionados still refer to them as - "laser" or "laser pointer". These "high power" laser pointer in power rates are much higher than a few hundred milliwatts.Class IIIb laser are considered powerful lasers, they are not the typical keychain laser pointer (less than 5 mW), the lasers can be found everywhere we strongly advice everyone to contribute to professional eye protection and to exercise extreme caution when using a laser. moreinfomation in FAQ.
The lasereshop.com helpdesk receives many questions. About all sorts of things. You can not name it, and the question has been asked. And the answer given, that too. Because the use of lasers show, that's dangerous or not? Melt your hand away when you 'touch' a laser beam you to pop balloons with a DMX-controlled laser, or is it all that bad? lasereshop.com tells you like more! First, it is interesting to know that there are different types of lasers. By the term "laser" we mean a device that is equipped with a laser diode, wherein the projection of the laser beam is visible (whether or not mid-air or on a surface).You would not expect given the size, but the well-known laser pointer is one of the most dangerous laser devices in circulation. At least, when it comes to a specimen with a relatively high power and in the wrong hands. In the past, these were freely available through sites like Marketplace, or through import from abroad. Due to safety reasons it is now more difficult to get here and it's not for nothing.A Laser Pointer Green has a laser diode. The laser pointers for presentations often have a red laser diode on board, often with a maximum power of 5mW. Sufficient to designate a specific projection on a projector screen with a visible spot. But remember well, a laser diode emits a concentrated light beam with a relatively very high intensity. In a relatively weak laser diode will be quite low with this.However, many people in many ways still arrive powerful laser pointers, sometimes with a power output of 200mW green at a wavelength of 532nm. You can imagine that the intensity of such diodes is considerably higher than that of a simple red laser pointer. Sellers often advertise these types of products with very attractive terms like 'shines up to 500 meters away, "or" beam visible at night! ". And that is not surprising, because high emissions of these laser diodes has a huge intensity! Indeed, the intensity of such lasers are often showcased on channels like Youtube. Balloons allowed to renovate, matches are lit and the radius goes through plastic bags around. Very nice, but also very dangerous when used in the wrong way. If such a laser has the capacity to soured a balloon, then it also has the ability to cause eye damage when there is with this type of concentrated beams is irradiated in your face. If the diode has plenty of time to burn can result in permanent vision loss. In short, you can therefore be blind!
