REFLECTANCE PROPERTIES OF PRESSED ALGOFLON F6 - A REPLACEMENT REFLECTANCE-STANDARD MATERIAL FOR HALON

The standard ultraviolet through short-wave infrared (200-2500-nm) dif fuse-reflectance material, Halon PTFE, type G-80, is no longer availab le. 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-reflectan ce properties of Halon and Algoflon F6. The measurements include spect ral hemispherical reflectance, spectral bidirectional reflectance fact or (BRF), sample BRF repeatability, and sample lifetime. (C) 1997 Opti cal Society of America.
