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...
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 ;)
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.
Yeah, the Chinese aren't well known for "truth in advertising" Its not a great burner by any means but will draw smoke on dark colored material at times.. My Dinsom blue burning laser has a warning label power < 5 mw, lol. Even with a couple more 0's wouldn't be accurate.
