Zinc selenide (ZnSe) is a classic infrared optical crystal material renowned for its low absorption, high transmittance, and uniform refractive index. It is particularly well suited for mid- to long-wave infrared applications and CO₂ laser systems, serving as a core optical material in infrared thermal imaging, laser processing, and medical equipment.
Main advantages
1. Ultra-wide infrared transmission band
2. Extremely low infrared absorption, minimal thermal effects, and resistant to deformation.
3. High laser damage threshold
4. Excellent optical homogeneity and no birefringence
5. Easy to process and form
6. Good chemical stability
Application areas
1. CO₂ laser equipment (core application)
2. Infrared Thermal Imaging and Temperature Measurement
3. Medical Lasers and Medical Infrared Devices
4. Aerospace and Scientific Research Optics
5. Infrared Optical Components
