Abstract

Variable-angle reflectance is an important spectroscopic technique. Certain samples such as opaque substances, films on opaque substrates, and films on liquids are tedious or practically impossible to analyze via conventional transmission spectroscopy equipment. The analyses of such samples by reflection spectroscopy, however, are straightforward.
