    Sale thread/ Hosts/Heat Sinks/Focus adapters/lasers

    Awesome laser. I love the heat sink. Just a nice simple reliable no frills 405nm burner and the purple host color is a nice touch.

    Looking for 520-525 1-1.5W Lowest divergence w/o correction

    There is no greens over 1w with that low if divergence. Your best bet is the plp520-b1. It's around 200mw and the divergence in my testing is under .5 mrad. The divergence of a 1w 520nm is about the same as a m140 445nm diode. Also your 405 is a single mode so you can't expect great divergence...

    FS: Sanwu Laser store - RGB handheld lasers, 405nm,445nm,465nm,470nm,505nm,515nm,520nm,525nm,635nm,650nm

    Podo I was looking at the 1.2 watt 520nm and the 1.2w 525nm. What the the differences in beam divergence, power. I noticed the 525nm is $40 cheaper and was curious if it would be worth going with that diode over the other one. Thanks, Alex
