Abstract
A reflectometer based on an integrating sphere operating in the 0.8-2.5-µm region is described. The reflectometer is of the absolute type and does not need a standard diffuse reflecting surface to obtain absolute reflectance values. The system is fully automatic, using computer-controlled circular variable filters as monochromators. Results for BaSO4 in the region between the visible and 2.5 µm show considerable deviations from the accepted values of reflectivity for this substance.This publication has 3 references indexed in Scilit:
