I had an old O-like 405/445 lens around, so I was putting on for some laser fun. when they are far away from the diode, they focus for a very tight spot in front of the laser, where it diverges terribly onwards, screwing it further gives a very nice beam.
Now, as I was screwing this in I noticed alot of odd looking things on my lens, that remind me of bacteria, is this actually bacteria? or just random things like dust, oil, etc?
I wouldnt have a clue where bacteria would have come from and deposited on the lens either.
Raw diode output:
Lens in place, defocused on my wall:
Looks cool and all IMO, but I wonder if it is actually bacteria..
either way.. that lens needs some serious cleaning.
