So my 405 nm laser "pointer" from eBay just arrived yesterday. This unit seems to be one of the less powerful ones as it doesn't burn anything or even sting my skin, but it's probably still more than the advertised 5 mW judging by the brightness of the dot. If I had to guess, I'd say the output is between 15 and 25 mW.
I don't have any 405 nm safety goggles, so I decided to use my 532 nm LaserShades for the time being. It didn't filter out as much 405 nm light as it did green light, but to my surprise, it still blocked out a significant portion of the former. However, I've read that goggles designed for green lasers are not effective for 405 nm light. Is that the case, or does it depend on the goggles?
