光学镀膜全面指南

光学镀膜是沉积在光学元件基底（如窗片、透镜、镜面）上的薄膜。通过控制反射、透射、吸收和散射，这些镀膜改变光与光学介质之间的相互作用，从而使光在各种应用中实现精确操控。

The Optical Transmission and Properties of Sapphire Windows

Sapphire Windows, often called Sapphire Glass Windows or Sapphire Optical Windows, made of single crystal synthetic sapphire (Al2O3), are becoming more and more indispensable in the exclusive fields of electro-optics due to their combination of superior optical, chemical, and mechanical properties. This article that Shalom EO presents concentrates on the optical transmission and the optical properties of sapphire windows, including the transmission wavelength range of sapphire, the transmission rate, the birefringence, and orientations. We have also analyzed the different growth methods and grades of sapphire crystals.
