Abstract

Stray light rejection characteristics of an optical system need to be carefully evaluated early in the design stage. Efforts to reduce the impacts of stray light can completely alter the optical configuration. The ability to produce acceptable surfaces of a given size is influenced by the required scattering characteristics of the optical elements. Sunshade requirements and associated baffle design also may often determine packaging dimensions. The usefulness of reimaging systems to control diffraction and thermal radiation is discussed. A brief review of the major tools used to determine stray light rejection characteristics of an optical system is presented. Examples illustrate the need to consider stray light characteristics at the first design phase for optical systems. The increased cost in time and complexity to modify a design originally based only on optical imagery is also shown in examples.
