The first camera I used was my girlfriend's old camera. It took a hit from a liquid sky a while ago and a few from this projector (so by no means a static beam). I'm not sure why it was so sensitive to laser radiation. In any case, halfway through, it died. :-? I'm not sure if it was laser related or not and I switched to another camera. You might have noticed not all of them have the burns.

Woah! I sure hope that camera wasn't expensive..... Was that done by direct exposure? I don't want to break my £300+ camera... Very nice build nonetheless - if only I had that much money...
Yes - it's just under the main 5V psu (from an older computer). The ILDA cable comes out and loops back in. I had ease of upgrades and interchangeability in mind during the build. It will accept any ILDA signal.

Yeah, I thought of doing that as well when I have a good case for my scanner. seems a bit easier IMO.
The beam on my red is about 5x8mm. I haven't measured the divergence, but I'd guess it's ~2mRad. The problem with gas, is twice the power is needed to achieve similar luminous efficacy unless it's a HeNe, which tops off at 100mW anyway. A 1W krypton laser is probably going to be 5 times or more (used) than what I paid for my red, and it'll take at least 1000 times more power in addition to 1 gallon per minute or more of cooling water. It also won't fit in a computer case.
DPSS requires about 6 times the power to achieve similar luminous efficacy. A 3W DPSS is much larger, inherently more than six times as dangerous, and thirty times the price.
There are 642nm modules available that would have decent specs, but they're also quite a bit more $.
I've kind of taken a liking to the white/yellow/magenta beam shrouded with a red aura anyway. You have to be looking for it to notice it, and even then, you can only see it in single beams. Andy'll tell ya - he's got one, too.
