kgpy (Kankelborg Group Python) is a library being developed by Charles Kankelborg's research group at Montana State University.
This library aims to provide general tools and utilities that can be used for the instrument-focused libraries such as esis.
See the documentation for a detailed description of the API and instructions for using
the various packages in this library.
The kgpy.optics package supports sequential geometric optics modeling similar to Zemax.
