ZnSe Protective Window

Ge Protective Window
To protect scan lenses from backsplatter and other workplace hazards, II-VI offers protective windows -- also known as debris windows -- that are either included as the overall scan lens assembly part, or sold separately. These plano-plano windows are available in both ZnSe and Ge materials and also supplied mounted or unmounted.

ZnSe protective windows feature our standard AR or DAR coating. Ge protective windows feature either our standard AR coating, or an optional diamond-like carbon coating (DLC) designed to withstand the most severe conditions likely to be encountered in industrial operations.
