There is a company which can print lenses, for prototyping optics.
I saw the company *Luxexel *on a trade show. They are from the netherlands.
They print lenses for custom optics. They claim they are the only one worldwide.
but I don’t know the max size and how heat resitance is,
180 x 380 x 20 mm and 60°C
Examples under https://www.luxexcel.com/optics-prototyping/showcases
I don’t know prices. But they use it on LEDs.
Has anybody experience with this products? I am a 100% noob in optics. Thoughts about it?
Depending on the price, maybe that is sth. for the modders?
