La description

Optical materials are solid substances that are transparent to visible, infrared,
or ultraviolet light. They are used in a way to redirect, modify or transform light
beams. Before the invention of the laser in the ***0s, Optical materials basically
referred to optical glass. In recent decades the infrared optical materials used
mainly for military applications, crystals and low expansion materials have become
a very important part of optics.This section systematically presents their optical,
thermal, chemical, and mechanical properties, and introduces potential device
applications.
