I havent verified the output but with the waterproof lens removed it is brighter then a verified 100mw green. Also divergence is typical rayfoss; nothing spectacular.
That a nice laser he got there. My 200mW was only around 75-80mW. It is in transit back to Rayfoss. My 500mW from them was up to spec though. I think maybe I got a dud with mine.
Theres a waterproof lens that you can remove if you wanna get more power and brightness. I like to keep it in though just so i can put the laser in my pocket or anywhere and not worry about getting dust in it.
1. yep its underwater, im holding it about 2 inches underwater(its hard to tell with the pic)
2. when i uploaded the pic it lost some quality so it looks funny
