Abstract

The performance of optical systems is often specified in terms of encircled energy. It is difficult to assign fabrication and assembly tolerances to such systems because there is no simple way to predict the combined effect of tolerances on encircled energy. This paper presents a new, simple formula which, while not exact, can be used to quickly give approximate answers to many tolerancing questions. It is based on diffraction theory and gives some interesting insights into how aberrations, surface figure tolerances, and environmental perturbatons affect encircled energy.
