    Need lens help for 405nm

    So does that mean I have a defective lens and need to contact Mohgasm? It only has 2 lenses inside, and does NOT focus the beam without adding the third lens. Thanks for the offer of help Fret, I'll be taking you up on that shortly. :) I have the heat sink, and I'll pull apart a DVD burner...

    Need lens help for 405nm

    Ah, Gotcha, thanks. I'm reading the threads in your sig. Gotta say bro, great work! I plan to build something similar to your $5 CPU heatsink build. I have lots of DVD burners and heatsinks laying around. What speed burner is my best choice? Now I just need to figure out how to build a driver... ;)

    Need lens help for 405nm

    The deer comment was just for giggles. I don't shine lights (laser or otherwise) at deer, it's illegal, and mean. I don't know what that comment was for originally, it is case negative. I don't have any wires going to the pill. Just the coil spring touching the positive on the battery. I just...

    Need lens help for 405nm

    Well, I got the lens, and hacked up the module to get it installed. I can now install the lens in various configurations, but none of them result in a "beam". All my other lasers throw a more or less parallel beam, that only diverges a little over long distances. This one is more of what I'd...

    Need lens help for 405nm

    That's really odd, I'm on the east coast US, and I go to that site all the time. Did you try searching by the sku #? Anyway, I ordered the lens from that site you linked, so we'll see if it helps. :) Thanks for your help, I'll be sure to report back with any progress.

    Need lens help for 405nm

    Thanks for the warm welcome, I was beginning to think no one would answer. :) I'll get the lens first and tinker from there. I'm no electronics whiz, but I am pretty handy with a soldering iron. If I can't make that lens work with the module as-is, I'll either buy another one and do a diode...

    Need lens help for 405nm

    Really? Works fine over here. Anyway, thanks for the lens info. So basically, if I get that lens, and maybe the aixiz module if the mount I have can't be adapted to fit the lens, then it should collimate the beam and allow me to focus? Sorry for the newish questions, I'm just getting started in...

    Need lens help for 405nm

    Hi guys, On a whim, I bought a cheap "100mW" blue (405nm actually) handheld laser from some random company in China. It should come as a shock to no one that it isn't anything like the description. It's supposed to be focusable, but the cap just unscrews and seems to have no effect on the...
