I recently purchased an NUBM08 450nm diode pressed into a 12mm module from DTR laser. Also got a complementary ACS5500BU driver pushing 4 amps into the module. I have experience with electronics and making things but this is my first laser and I am a little scared of its power (should have gotten a lower power laser diode!).
I purchased a set of "Eagle Pair" safety goggles, OD6 190nm-540nm but when I shoot my laser at wood it still really hurts to look at it. I know wood is slightly reflective but I feel like that's a reasonable thing to shoot at with a burning laser (or not? Styropyro may be a bad benchmark).
TLDR:
Why does it hurt to look at the laser's dot/reflection on wood and other things, is OD6 not nearly enough for a laser of this power? (4-5 ish watts).
PS: its got the G8 M9x0.5 threaded lens but the beam quality leaves something to be desired. Is it the diode, lens, or just my expectations? leaves ~0.5 cm squared cube 10 feet away at best.
