Green laser pointers and accessories. Green laser pointers is probaly the second most used items used by Amateur Astronomers. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool. The green laser beam dot can be seen at much greater distances than with a red laser pointer. For all the techies out there this green laser pumps out 20 mW of intermittent power that is much more powerful then other economy pointer you may see web. What does this mean? It means you can be confident your laser will shine a constant beam up to 5km with visibility that far exceeds that of your typical red laser.
Warning
The 20Mw green laser is more than 1000 times brighter than the Sun's image on the eye, and will damage your eye with direct exposure. Always use with extreme care and the right eye protection.
