Paper Abstract

A reflectometer was designed to measure reflectivities of sample areas ranging from 10 microns to 1 millimeter. It is capable of illuminating the sample from any angle between 0 and 45 degrees relative to the surface normal, with the observation angle always normal to the surface. The instrument was calibrated and tested using reflectivity standards. Plots of reflectivity versus illumination angle are presented for some common materials.
