Paper Abstract

Controlling stray light through the use of black surfaces is common practice in the design of astronomical instruments and telescopes. While the geometry of the elements that make up the stray light design – baffles, enclosures, masks, etc. – is key, so too are the materials and coatings used to make them. We present a survey of reflective spectra from 250nm to 2500nm of a range of materials used for stray light control, as well as other materials commonly found in instrumentation and telescopes.
