Package contains optical similations and calculations for prisms. There are two representions;

• Analytical: properties of prisms based upon pure math and physics
• pyOpTools: description of the optical system in pyOpTools

In the old folder, there is a numerical verification for the Strehl ratio formula;

• rayOpt: description of the optical system in rayOpt

python3 setup.py develop --user

A jupyter notebook is available in the notebooks folder. This can be converted to notebook as follows

jupytext --to notebook *.py

Install depencies using poetry. Pyoptools must be installed via pip
'''poetry run python -m pip install git+https://github.com/cihologramas/pyoptools'''
The pip install avoids error. Another fix would be to change pyoptools.
Firefox does not work. Renders can only be made via jupyter lab.

Optical design is described in the video

G2 lens specs can be found online....
6.33mm diameter, 5.3mm front surface, 4.0mm focal length
Working Distance: ~2.4mm from laser diode
Several issues
- requires you to know aspheric coefficients AND divergence / sice point
- mitigated by assuming parallel bundle

• there is no proper bridge for object from FreeCad to pyoptools
• first side of mirror is at origin
• I have problems rotating the in z-direction in the PyThreejs viewer
• If light hits the prism at an edge corner, it does not know what to do and does not throw an error.
• cylindrical lenses, do not have side surfaces in pyoptools
• it is not possible to load cylindrical lenses directly from Edmund's library
