Sharp 395nm 300mW Diode GH0393AA2G

look into a beam ??????? I do not care what the power output is........You are teaching the uninformed a dangerous practice. Just saying.

I agree with you. I only do it in a safe-ish way at below 1uW, but I agree it's definitely dangerous to suggest, and most folks don't have the tools to attenuate a beam safely to try to replicate it, so it's extra hazardous to attempt and shouldn't be copied.

Thank you for your understanding. And, I consider your analysis very interesting.

I have a 660 nm laser that output less than 5 mW. I shine it on a convex mirror that spreads the beam and allows me to look into it safely. But, that's just me.

And then there are those that purposely stand in front of a 5W laser to watch beam shows
