Abstract
Infrared (IR) Bi-directional Reflectance Distribution Function (BRDF) curves from bare super-polished hot isostatic pressed (HIP) beryllium (Be) and chemical vapor deposited (CVD) silicon carbide (SiC) mirrors are much higher and have drastically different slopes than those predicted from either visible (VIS) BRDF or surtace profilometry data. The end result is that current state-of-the-art HIP Be and CVD SiC will not meet some low scatter requirements. This paper presents data showing that this anomalous IR scattering effect can be easily "covered-up" by coating the bare super-polished substrates.
