Abstract

A wide range absolute specular reflectometer of simple design has been built to measure the absolute reflectivity of single crystals at liquid nitrogen temperature. The basic design, theory of operation, and inherent limitations of the design are discussed in terms of the spectral and temperature regions attainable.

The instrument built at the Institute of Optics is shown as well as samples of measured reflectivities.
