I have a violet laser for sale. i know you guys are tech wizards and can build them yourself but I would like to sell this one I built. The brass body is actually a 3 piece glass lens from mi-lasers and runs off of 6volts. the collimation is remarkably great. Seems a bit dim I guess its from the internal reflections of the lenses. or that violet is hard to see. I am asking 125 dollars for it including power supply you may PM me with your best offer.
