Znse window


He Rui optics' ZnSe (Zinc Selenide) window is a transparent optical component made from zinc selenide crystal. ZnSe is a widely used material in the infrared (IR) range due to its excellent transmission properties in this spectral region. It is particularly suitable for applications that require transmission in the near-infrared, mid-infrared, and far-infrared wavelengths.

ZnSe windows are commonly used in various optical systems, including:

  1. Infrared Spectroscopy: ZnSe windows are used in IR spectrometers and Fourier Transform Infrared (FTIR) systems because of their high transmission in the IR range.

  2. Laser Systems: They serve as protective windows for laser cavities and optical paths in laser devices, especially those operating in the IR spectrum.

  3. Thermal Imaging: ZnSe windows are used in thermal imaging cameras and other IR detection systems.

  4. Optical Communication: In fiber optic communication systems, ZnSe windows can be used for interfaces and other optical components that require IR transmission.

  5. Aerospace and Defense: ZnSe windows are used in sensors, telescopes, and other optical instruments on board aircraft and satellites.
