good quality expensive price
I bought this laser module to build into a laser projector. The beam divergence is quite high, but I think this can be lowered by adjusting the lens a bit. Output power appears to be correct. I don't know for sure if this laser leaks infrared, so I added a filter, but still it can give you skin burns or burn paint off objects. Also TTL response is good, quick blanking, very little fade out lagg. The Included goggles appear to block the laser quite well, but professional goggles are recommended with these high power lasers.
