Honestly walk to your local RadioShack and buy a red pointer. Go home and fog up a room. And bingo! Visible beam. Greens have IR leak and you don't want that. Get used to lasers and such before you go for power.
Warnlasers is just as bad... Opto or LG. And how can you say that the IR leak of a 50mW green laser is not dangerous? Unless you're suggesting that 30mW+ of IR in the eye is not an issue?
Brilliantly written i was thinking what to write when you got in first,i had something i had to really do first so i didn't post. i don't think you missed a thing +1 if system allowsGood god, you people.
First of, if your IR leak composes over 60% of your entire output, then damn! Not even DX sells crap that bad.
Worst IR leaks percentages, to the best of my knowledge, are around 25-30%.
So that's only around 15mW or so realistically, from a 50mW greenie.
Even IF those 15mW of IR were focused (which it is not, it diverges like crazy), YES I am precisely saying it's not an issue.
Please people, get facts straight. Spreading paranoia is getting worse by the day here. We got from "You may want goggles for Class IV" to "You don't want green lasers at all because they leak some IR. Also if you click "Buy" without having OD19 safety goggles, your eyeballs will f**king explode and and your kids will get cancer".
There is a good dose of sanity and caution, but currently where the forum is at with safety advices... it's just plainly insane.
