Customer ratings for BDR-S06J 405nm, 500-600mW Blue-violet Cut-pin Laser Diode (TO18 5.6mm)

Nice clean single mode beam low divergence with the 3 element lens very stable!
These are very resilient diodes and seem very happy at 400ma don't really get hot if not pushed tg a high duty cycle excellent for light duty engraving work also.
