Just curious, but can you post a link(s) to beamshots which approximate what you are trying to do? I'm just not familiar with the whole diffused aspheric concept at all.

I don't have any beam shots and the light is at work right now. I'll try to remember to get some soon.
The concept is simple though. Thor Labs just took 1500 grit sandpaper and roughened up the flat surface of the aspheric. They went a little too far or rough for what I wanted, but it makes for a very nice beam profile.
I believe so. I'm going to try it out with one of the two aspherics that I just got in the mail. I'll let you know how it goes. I'm just going to use plain super fine grit sand paper on a granite surface
It may even be possible to do a hybrid lens using a fine grit and a small media blaster. For instance you could treat the outer portion of the lens with the grit and leave the center clear. That's the best way I've come up with to get rid of the square LED die image for aspheric lenses while retaining most of their throw.
If you want to keep the hot spot and just have wider spill leave a narrow ring clean right at the edge near the bezil, that is where the hotspot is created, and everything else will get diffused
Interesting! I'll see if I can try that with DC Fix. I'm pretty sure I'm going to order new lenses though and that means I'll have snow on the ground by the time I'm ready for beamshots!
just joined up. hobby cyclist needs lights and cant pay top dollar so happy going diy!
since I also bought a pair of ebay china magicshine clone and then decided to look how to improve the beam pattern, I also sourced and fitted the wide angle lens to my 2 bar mount and a google of frosting lens found me here, at an active thread, not something 3-10 years old haha
Beware, there is a disease called “flashaholism” that is running rampant here. If you stick around, you will be infected by the disease. Then, you will not be able to stop buying more and more flashlights until you learn to build them yourself. Then you won’t be able to stop buying parts for flashlights! You have been warned! Welcome to BLF! :bigsmile:
I’m a little late to the party, but sometimes the symptoms to manifest differently: Once infected you may start purchasing parts before learning to build lights. You’ll still have an empty wallet, but in that case you don’t even get any fancy lights (until the disease progresses to stage 2).
