Research on low sub-surface damage detection of hard brittle optics materials

摘要

This paper is a low sub-surface damage detection method for hard and brittle optical materials. The method is based on the preparation of the test instrument and the detection of the surface damage of the sample to obtain the Brewster's angle of the sample to be tested and further utilize the Brewer The surface roughness of the sample is characterized by special angle. The method has the advantages of high accuracy and high detection method, and the detection method is simple and fast, and the surface of the sample to be tested is not damaged. This method can also be used to measure the other micro-surface structure of the optical element and to detect the surface microstructure. preparation of high quality high damage threshold of films. template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text.
