Abstract: A differentiable ray tracing package for transmission electron microscopy built on JAX. Optical systems are described through the Jacobian (ABCD ray transfer matrices) or Taylor-expansion coefficients of the ray coordinates through the system, enabling, for example, the verification of coordinate systems and descan error in 4D STEM shadow-image experiments.
