I suppose they are right angle prisms with a dielectric coating. Probably custom made for kvant???
"its called character briggs..."
these diodes looks very interesting...
Sorry Jenny, but we can't buy la<ers from China anymore because US custom< are seizing them all at the border right now ..
I bought a 532nm from china a couple weeks ago without issue
just make sure they don't include a power supply, should help your case that its an OEM device
got my $60.00 638nm 500mw diode. Not powered it up yet but I am hopeful that it will be something to use for beams if nothing else.
Where did you acquire a ML501P73 for $60 may I ask? The 300 mW mitsu diodes are $65 ..
nope your right. PS: just put power to the laser diode. Damn bright at 400ma. Will never work for graphics. Not so sure about beams either. It appears to be about as bright as 4 642nm diodes at 300ma or about 600mw of 642nm. It would be the fix if it could be tamed. 2 of those and you done.
