Zinc Selenide (ZnSe) Applications

  • Due to its high transmission in the mid-infrared range, ZnSe (Zinc Selenide) is well-suited for CO2 lasers and other infrared applications, making it an excellent choice for optical components.
  • Used in thermal imaging systems as a lens material due to its excellent transmission properties in the 8-14 μm wavelength range.
  • ZnSe optical fibers are used for transmitting infrared light.
  • ZnSe detectors are employed in X-ray and gamma-ray spectroscopy due to their high-energy resolution and superior gamma-ray detection efficiency.
  • ZnSe is also used in semiconductor devices, including infrared light-emitting diodes (LEDs), laser diodes, and detectors operating in the IR region.
  • ZnSe thin films can be deposited on various substrates using techniques like sputtering or chemical vapor deposition (CVD).

Zinc Selenide (ZnSe) Packing

Zinc Selenide (ZnSe) is carefully packaged in carton boxes with foam protection to minimize damage during storage and transportation and to preserve the quality of our products in their original condition. The vacuum packing is 1kg/bag, 25kg/barrel, or based on specific requirements.
