Is there any chance of you posting some more info about the optics block?
I've been playing around with an RGB laser set (red diode, green DPSS,
BluRay/HD-DVD playback diode) and I'm curious how you got the spot size
down. The best I've managed is about 0.5mm, which is nowhere near small
enough to get any reasonable amount of resolution (about 50DPI by my
reckoning)...
Thanks,
