I'm under the impression a neutral density filter could cut beam power down significantly, and at a 1.5 density effectively turn a 100mw laser into a 3 mw laser. But is that ok to do? The glass absorbs the light, but I can't imagine it having an issue with up to 200mw.
Also, am I right on the effect of the filter? 1.5od has a ~3% transmittance. Captain Obvious would say it's 100mw x .03....but who know? i'm still a noob. Would somebody please confirm?
