So as some of you know from irc, I am sort of addicted to buying expensive lasers. Well today at work I set them all up on a milk crate and took two pictures that look pretty awesome. I wanted to share them with you guys.

They are in order from left to right
150mw red (650nm), 350mw red/orange (635nm), 50mw green (532nm), 1W blue (445nm), and 200mw purple (405nm)





There are 5 lasers there, but the purple one is kind of hard to see because 405nm light is very weak to the human eye.

I was about to say, where's the purple one?! XD Cool lazers man. :thumbsup:

A camera isn't a human eye, though. OR IS IT

yeah...
most cameras can even pic up infrared light
something the human eye can't see...

if you don't believe me, use your phone camera to look at the dome on top of the remote control while you press the buttons...

If they can pick up infrared, they should be able to see purple...

anyway,
cool lasers
just watch out for/don't blind the pilots of any planes
:3

Slushba you have a good point about cameras picking up infrared light, however, infrared light would be at the other end of the spectrum. The human eye can pick up somewhere between 405nm-808nm light, the 405 being purple, and the 808 being a really dark red. Anything higher than 808 is considered infrared, anything lower than 405 is considered ultraviolet. So the light that the camera didnt pick up in this picture is not infrared, but borderline ultraviolet (which in my experience cameras have a hard time picking up).

You are correct. Thank you for the information.

you can just about see the purple one in the first picture

Erm... I'm pretty sure that gamma radiation CAN penetrate earth's atmosphere, considering it takes about a foot and a half of lead to stop a single particle of it.

gamma radiation is a wave, not a particle.
