I bought a Chinese PM-851 2000 mW green laser. It didn't come with the battery so I'm running it off 3 AA cells instead of the 3.7v that couldn't be shipped on a plane. Anyway.... I need it to burn aptasia pest anemones in a saltwater aquarium and there's no lens on it. Without a lens I can't concentrate the beam enough to light a match let alone kill a pest coral.
Any DIY options out there?
Suggestions?
Thanks.
