ZnSe is a kind of popular infrared material. Its optical bandwidth can be 0.6-20 μ m. Its absorption in infrared light is low, and can also pass visible light. ZnSe is mainly used in infrared detector and laser systems.
Opticreate produces high-precision ZnSe window and lens, could do AR coating,HR coating and Beamsplitter coating according to customers' requirements.
