Hi, I need help with designing a doublet lens. I have a front lens already designed, but I need the back lens design to be done in CST. I have provided some notes and a code that generated the front lens. I also provided the phase profile of the front lens, as I need to get a matching profile for the back lens for Achromatic or off axis focus.
Please also test the lens & simulate in CST to prove it works.
