The ZnSe Infrared Crystal (Zinc Selenide) is a chemically inert, non-hygroscopic optical material engineered for high-power laser systems. Laser technicians choose the ZnSe Infrared Crystal because it provides exceptionally low bulk losses and high resistance to thermal shock. This makes it the leading choice for CO2 laser optics operating at 10.6 microns and high-resolution thermal imaging systems.

  • Ultra-Low Absorption: Minimizes thermal distortion in high-power laser windows.

  • Broad IR Transmission: Delivers clear, high-resolution imaging from 0.5 to 19 µm.

  • Environmental Stability: Non-hygroscopic and chemically inert for reliable field use.

Description

ZnSe Infrared Crystal

The ZnSe Infrared Crystal is a highly pure optical material. It excels in applications requiring multispectral imaging and high thermal resistance. This material is a primary choice for high-power laser windows and forward-looking infrared (FLIR) systems.

Core Material Advantages

  • High Thermal Shock Resistance: This material handles the intense energy of industrial lasers without cracking. It ensures constant safety in high-power environments.

  • Broad Transmission Spectrum: The crystal offers a wide transmission range from 0.5 to 19 µm. It displays excellent imaging characteristics across visible and infrared bands.

  • Chemically Inert Composition: It resists moisture and environmental degradation. This eliminates the need for complex, specialized storage enclosures.

  • Extremely Low Bulk Losses: Minimal energy absorption prevents thermal lensing. This maintains perfect beam quality during operation.

Advanced Optical Engineering

Our crystals deliver the precision required for elite industrial and military applications.

  • CO2 Laser Optimization: This material serves as the benchmark standard for optics operating at 10.6 microns.

  • Multispectral Versatility: It supports a wide variety of infrared components including beamsplitters, filters, and lenses.

  • Spectroscopic Precision: The uniform refractive index makes it excellent for demanding attenuated total reflection (ATR) prisms. For deeper standards on infrared optical materials, you can consult the Optical Society of America / Optica.
