Where can I find a lens for my laser? Answered
I'm building a laser gun and I would like a lens for the laser to shine through. How much of an effect would this have and where can I find a lens? Could I salvage the one from my broken galaxy player's camera? Also, what would the effect be to feed the laser extra power? Right now, it runs off of three button batteries, like the cheap ones packaged with many things, but I would like to run it off of a battery bank with four AA batteries.
