I used OpticSim.jl [1] in the past and it does the job. The documentation is far from perfect, but it's really capable. I managed to reproduce subtle distortions observed with Zemax in hyperspectral imagers. There is also a python ray tracer that I didn't have a chance to try, but it seems that the development has stopped [2].
