A VACUUM INTEGRATING SPHERE FOR IN SITU REFLECTANCE MEASUREMENTS AT 77K FROM 0.5 TO 10 MICRONS

Abstract

A modified integrating sphere with a spectral measurement range from 0.5 to 10 microns is described. This integrating sphere can be used for in situ reflectance measurements of low temperature surfaces at vacuum conditions. The techniques employed in measuring the spectral reflectance of CO2 cryodeposits are discussed. Reflectance data for CO2 cryodeposits on stainless steel and Cat-a-Lac Black substrates are presented as a function of wavelength and cryodeposit thickness. The reflectance characteristics of the sphere's internal coating of NaCl are also presented.
