Hey guys, I have a couple of 591nm laser modules that I would like to put into my lumia projector. I like to fade in/out my lumia effects and also control the brightness. These summation lasers don't work well, or at all, at low power levels so fading/attenuating via modulation is out. Since we're talking gradual fades over the course of a half second of more, I don't need fast "blanking". What's a good way to mechanically attenuate a beam? I know in the good old days it was either a galvo/retro reflector or an AOM. I have some of the old Stocker Yale GM20 knock-offs. I was thinking of just using a flag on one of those guys. Since the beam is going into lumia glass, I don't think I need to worry about aberrations from the edge of the flag, right? If anyone has a better idea, please let me know.
