Abstract

APART is an industry standard computer program for calculating the stray light reaching the focal plane of a system. APART was originally designed to only calculate the stray light for axially symmetric optical systems. However extensions have been programmed into APART that allow an off-axis system to be modeled as well. This paper describes in detail the conventions and techniques that must be followed in order to accurately model an off-axis optical system in APART.
