The low power Green laser Pointer can always be used to watch tiny spot in low

It would be an interesting thing to do astronomy research with this pen style laser. The 532 nanometer Powerful Laser Pointer gadget can always omitting a strong and bright beam, which has made it possible for astronomy lovers to watch stars and other celestial objects several hundred miles far away. The low power Green laser Pointer can always be used to watch tiny spot in low clouds and do some help in our daily life.

Laser Pointer Green is now the world's most popular laser pointers, because the green light than red light 6 times more than red light beam significantly, while the price is much cheaper than the blue and yellow. Green pen is the wavelength of light emitted 500-550nm, the wavelength sensitivity of the coefficient table, as is the closest one wavelength. Green is undoubtedly efficient light source, the eye more easily identified. The green light sensitivity of the human eye is higher than a lot of red; the other is green light scattering in the atmosphere more than red light. Red laser pointers, wavelength 630-670nm green laser pointer is more for longer.

The laser injuries Dr. Shepard Bryan has seen at his practice in Mesa, Ariz., involved red lasers, which many laser fans consider passé.

A green laser, its beam visible along its path, is even more dangerous. Green is more easily absorbed by the retina than red, so it requires less exposure to cause damage.

If they don't have the IR filters, the lasers burn more easily. However it may damage your eyes, because the invisible rays are not blocked, they're bounced off walls.

like this deal on a 300mw laser pointer red . Most laser pens and pointers are red with only the dot visible. With the green laser pen, the entire beam is visible, not just the dot. The green laser pointer is great for exercising pets, pointing out star constellations and impressing your friends and family. So stop with the silly little red laser dots and go forward with a green laser beam.

The apparent brightness of a spot from a laser beam depends on the optical power of the laser, the reflectivity of the surface, and the chromatic response of the human eye. For the same optical power, green laser light will seem brighter than other colors because the human eye is most sensitive at low-light levels in the green region of the spectrum (wavelength 520–570 nm). Sensitivity decreases for red or blue wavelengths.

Green Laser 10mW are hand-held, pen-like and battery-powered devices that can project a laser beam for the purpose of highlighting key locations at a distance or areas of interest on the screens during presentations. Commonly available laser pointers emit red coloured light although more expensive pointers which emit green or blue light exist too. Red light laser pointers usually come under the laser classes of 1, 2 or 3A, with beam power up to 5 milliwatts (mW).
