Principles of Diffractive Homogenizers

A beam homogenizer, also called an optical homogenizer or diffuser, is an optical component that generates a uniform distribution from the input beam projected onto it. The laser homogenizer applies a random or quasi-random modification to a single-mode or multi-mode input beam to diffuse the irregularities. Therefore the output beam has a well-defined near constant … Continue reading
