Enderman would know. But nice aspherics cost lots of money. :money_mouth_face: :money_mouth_face: :money_mouth_face:
One alternative is to mirror your own glass. Rustoleum has a mirroring spray-paint now. If you’re sure the mirror you have is the right shape, you might be able to clean off all that messed up coating and re-coat it with Rustoleum Mirror Effect paint.
Hmmmm… looks like it could be pricey for an aspheric. I might save a few bucks at thorlab instead of Edmunds but a uf-1504 (or is it 1405???) Would still work out cheaper.
That mirror paint is a good idea but will add more time to the build.
Hey, still a month to go!
Then I might still join the contest afterall.
I’ll have a good look tomorrow into what i have laying around to make a light out of.
Could be a triple on a 20700 and sideswitch, maybe USB charging port.
I’ve got plenty of drivers. I don’t know if one of them could get to the Netherlands in time to help you, but hit me up in PM if you want to talk about it.
