Abstract

The process of diamond-turning makes possible the manufacture of large-aperture, long effective-focal-length collimators that are compact and lightweight. These properties make such collimators an excellent choice for automated testing of military electrooptical sensor systems. A series of experiments which were performed to analyze the use of diamond-tuned collimators in laser beam divergence measurements are discussed. The experiments show that beam divergence can be measured to high accuracy using diamond-turned collimators
