Paper Abstract

The new Off-Axis Rejection Design Analysis Software (OARDAS) aids in modeling complex baffle configurations for generally asymmetric and folded optical systems in order to estimate their background suppression performance. This interactive program uses real raytracing and a combination of Monte Carlo and deterministic methods to aid the user in finding stray radiation paths and calculating stray backgrounds. User friendliness and flexibility were two primary goals in the program design. With its extensive graphics capability, OARDAS is a powerful tool for diagnosing and understanding complex radiation paths. This paper first gives an overview of OARDAS philosophy and capabilities and then shows how OARDAS is used to analyze a complex baffle design.
