Ok it took me a while to dig up exactly what lens I bought and it's a 405 G2. From researching this forum it appears that this is not an ideal lens for getting more of a dot out of an m140 diode. Apparently the G1 lenses "clip" the wings somewhat and the aixiz 405 glass do the best job of...

Yes I'm using the 3 element lens. I think I've got the focusing down now that I've cut the heatsink down to add a focusing ring. I can focus it to a crisp bar at 15 feet and the bar will pop a balloon at that distance after a few seconds. It is an m140 diode. I'd like to pop at greater...

Hmm. So I need some correcting optics. What would that entail? Is it another lens in use along with the one I'm already using?

Here's the latest - the heat sink consists of 5 "ribs" and the lens sits completely down inside of it. So far it has not gotten remotely warm as it's only on for a second at a time. I cut off two of the ribs which allows the lens barrel to sit outside of the heatsink enough to get a focusing...

Ah I didn't think of using tweezers; that's a good idea. The Star Trek sound boards was taken from a new toy phaser off of eBay. You can buy them all day long for $10-$15. They are light blue instead of the screen correct colors. The only issue with it was that the trigger directly touches...

The glass lens I tried initially was a 3 element lens from eBay so I can't attest to its quality. However, it did appear to suffer from the same problem I have with the acrylic lens in that if the balloon is 6 or so feet away and the focal point is too close to pop it then a turn of the lens...

Here's the project so far:

Ah, let me clarify - my module is aluminum and the lens holder is plastic. Attempting to focus the lens requires inserting something into the module and its gouging the plastic that is holding the lens. If you're trying to pop a balloon from 20 feet away but the lens is too close to the diode...

Hello guys, new member here. I've lurked around this forum for a long time but have now joined in an attempt to get some help with my build. This is my first build and unless something changes it'll probably be my last. I got the bug to build a functioning laser gun from youtube videos a few...
