    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.

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...
