Evaluation of Nearly Parallel Light Beams Using a Penta-Prism.

Abstract

The use of a penta-prism to measure the divergance of different elements of a collimated beam of light is analyzed. Measurements of the beam from the Airborne Optics 23-inch collimator show the maximum divergance of rays from parallelism to be about 0.000030 radians. (Author)
