Values of the Optical Constants for Beryllium, Magnesium, and Zinc

Abstract

Reflectivities of evaporated metal films have been observed under varying conditions, allowing the computation of conductivities and dielectric constants by a previously described method. A reflectometer employing both a photo-cell and a thermopile permitted measurements in the visible and near infra-red regions. Curves are included showing the values of the constants for beryllium, magnesium, zinc, and copper. Comparisons are made with other published results.
