Reflectance properties of pressed Algoflon F6: a Replacement reflectance-standard material for Halon

摘要

The standard ultraviolet through short-wave infrared (200-2500-nm) diffuse-reflectance material, Halon PTFE, type G-80, is no longer available. Therefore an equivalent diffuse-reflectance standard material must be found. Algoflon F6 is shown here to be an appropriate replacement through the presentation of measurements of various spectral-reflectance properties of Halon and Algoflon F6. The measurements include spectral hemispherical reflectance, spectral bidirectional reflectance factor (BRF), sample BRF repeatability, and sample lifetime.# 1997 Optical Society of America
