Silicon Windows

Silicon (Si) optics are primarily used in the 1.1- 7?m range. Silicon is ideally suited for weight sensitive applications having a Density of 2.329g/cm3
Silicon is typically used in the 3 - 5?m for Thermal Imaging Systems
Our Silicon Optics are available with AR/AR or AR/DLC coating options typically for the 3 - 5µm region

Specific coatings options are avilable on request
