Could be manganese

Do you have a 365nm light source? What wavelength was used in that picture?

Interesting and timely topic as I was just about to post about UV lasers, a real UV laser not a cheap 405nm laser pointer. On one of the uranium glass boards another member is talking about using a UV laser when he goes looking for Uranium glass. I was kind of skeptical that a "UV" laser...

Brown Recluse would be a fair target. So are flies..

I found an Amazon replacement lens. Optically it works fine. Mechanically its a bit too long. I thought the threads in the crown were tapped all the way through, but they are only partially tapped, and the lens bottoms out. With the laser completely screwed together, it wont really achieve...

Thank you

Its funny cause it worked the last time I used it, and then the next time, all messed up. I dont usually run for a long period of time. Shrug, who knows ;)

Let me get some calipers and a thread pitch gauge and go from there.

Yeah, I don't either, or which lens to get, hence the post.

I've bought a couple 301 style lasers on Ebay. They work fine. Bright as heck

There is the laser, The crown is removeable and the lens in threaded into the crown. No idea what damaged it..

I have an Amazon Special, Dinsom brand blue laser. It has an adjustable lens in a brass holder that screws into the crown of the laser. It has somehow become damaged, would someone be kind enough to point to a suitable replacement, Pictures if need be. Thanks.

That's pretty

Are you saying you had bad customer service from them, or asking if anyone else has??/

50 milliwatts perhaps, not 50 watts...
