Abstract

ABSTRACT Measurements requiring very high photometric dynamic range, like astronomical observations of faint objects near bright sources (e.g., extrasolar planet detection), are often limited by the scattered light characteristics of the telescope. Although the light‐gathering power of recently built telescopes has increased dramatically, their scattered light performance has not. We compare models and measurements of telescope scattered light and discuss some of the scientific and technical issues that suggest how a low scattered light design could extend the scientific capabilities of moderate (4 m aperture) telescopes.
