Could this be used as a simple lens designer? Or are there better programs for than?
- iFreilicht 6y agoSeems like it, rays seem to be accurately refracted between object boundaries, depending on the optical index you set for that object. Pretty cool!
- hutzlibu 6y agoSpeaking about it, has anyone experience using a laser cutter to create fresnel lens, out of transparent plastic? At some point I want to do this, and this plugin might seem helpful.
- ginko 6y ago> Or are there better programs for than? There's the rayopt[1] Python library. You can find a repo of notebooks modelling a bunch of lenses from the original patents here[2]. I've played around a bit with that myself, modelling a Voigtländer Color-Skopar.

Take a look on Etienne de Foras'[0] Astree[1] (an amateur telescope making FLOSS app to help with optical design and optimisation) and on Foucault2[2] (an amateur telescope making FLOSS app to help with mirror design and polishing). Astree in most cases is enough alternative to proprietary Zemax (+ Astree already support ZMX file format).[3] [0] http://edeforas.free.fr/?cat=6 http://edeforas.free.fr/?cat=6 [1] https://github.com/edeforas/Astree https://github.com/edeforas/Astree [2] https://github.com/edeforas/Foucault2 https://github.com/edeforas/Foucault2 [3] https://github.com/edeforas/Astree/issues/28 https://github.com/edeforas/Astree/issues/28
- buildbot 6y agoThese both look really interesting too, thanks!
