"As a part of the investigation of classical reflectance, it is determined that the hemispherical reflectance for a material with a particular pair of optical constants can be approximated by computing the angular reflectance at sixty degrees, using Fresnel's generalized reflectance formulas.
Reflection methods for the purpose of determining the optical constants of a variety of materials are discussed. The unpolarized reflectance versus angle of incidence technique is used for determination of the optical constants of bulk solids. Restrictions on the simultaneous solution of the Fresnel equations are determined and a computer program is developed to compute values necessary to plot the isoreflectance curves. Error studies are carried out for the case of the optical constants close to those of aluminum at 0.59µ to determine the effects of small errors in the reflectance values on the resulting values of n and k.
The method is applied to the case of an aluminum first surface laboratory mirror and the optical constants are determined to be 1.09 and 6.37 in the wavelength range around 0.55µ"--Abstract, page ii.
