> Could this be used as a simple lens designer? Or are there better programs for than? 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
