Comprehensive optical design, optimization, and analysis in Python, including GPU-accelerated and differentiable ray tracing via PyTorch.

A fast transfer matrix method written in jax for modelling optical multilayer thin films

POCAL (Python Optical Coating Analysis Library) allows to easily design optical coatings both as single layer and as multilayer stack, monitoring a wide variety of optical properties and, moreover, giving the possibility to automatically refine the multilayer design to achieve the desired optical goals.
