Zinc Selenide > Mirror ZnSe

Introduction

Zinc selenide (ZnSe) is the most popular material for infrared applications. Due to very wide transmission range covering 0.6-22 µm chemical vapor deposition grown ZnSe as a high optical quality material is used to manufacture optical components (windows mirrors lenses) for high power IR lasers.
