DIY AR coating

Flashlight Modding and DIY Parts

I have several lights that don't have antireflective lenses and I would love to know if there is a source for AR coating you can apply yourself.

Anyone know of a source for something like this? A spray-on type coating, maybe?

Thanks,

Rich

I'm affraid AR coating is a bit more difficult... vapor deposition and such, because you would need very thin layers. I don't think this is possible with a spray. But I would buy one if there was!!

The only place i know for more exotic sizes in AR-coated lenses is this:

KaiDomain has AR lenses pretty cheap. People have done tests showing 8+% more lux using AR lenses. I've upgraded most of my lights, but I can't really see any difference.
