The 80mw red 650nm looks reasonably OK in dense fog but it is basically worthless in light fog. I watched your video ChipDouglas and at first I couldn't understand how those people were not blinded. But then I got to thinking... if the optics were such that the beam were quite wide instead...

Sorry, I was trying to say that money is a concern but, even if it were not, I'm not sure I could get a good combinaton of a safe power level with a long duty cycle. I checked the specs of several RGB scanners and they all used lasers with > 200mw of power. So I infer this means that a) RGB...

Thanks for that calculator JBTexas... it looks like bad news for me. It appears that the 80mw 650nm red has only 14% the beam visability of the 30mw 532nm green. That seems about right from my subjective point of view. I would like the alternate beam color to be at lease 3x brighter than...

Back story: I love to dance so I have disco lights and a fog machine in my home. The laser is a $99 "Micro Galaxian" by American DJ. It has a 30mw 532nm green laser and an 80mw 650mw red laser. They shine through a pair of diffraction gratings, one of which spins. This creates approximately...
