No, it’s not red – it’s green
Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we’re pretty sure you want to be a superior geek – and doing it with a green laser is the way to go.This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, 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 as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer.
