ZnSe custom made optical

Custom ZnSe optics for CO₂ lasers, infrared imaging and spectroscopy

Zinc Selenide (ZnSe) Optics

Zinc selenide (ZnSe) is a versatile infrared optical material combining broad spectral transmission with low absorption at important infrared laser wavelengths. It is widely used for CO₂ laser optics, infrared imaging, thermal sensing, spectroscopy and other applications requiring transmission from the visible region into the infrared.

Physix supplies custom zinc selenide optics manufactured according to customer drawings and optical specifications. Components can be produced as lenses, windows, aspherical elements, prisms and other precision IR optics, with coatings optimized for the required wavelength range.

Why use zinc selenide for infrared optics?

Zinc selenide is a polycrystalline optical material with a broad transmission range and relatively low absorption in the infrared.

Key advantages include:

  • Broad optical transmission from the visible into the infrared
  • Excellent performance at 10.6 µm
  • Well suited for CO₂ laser systems
  • Useful for MWIR and LWIR applications
  • Low bulk absorption at important IR wavelengths
  • Allows visible alignment light to pass
  • Suitable for lenses, windows and aspherical optics
  • Compatible with broadband and laser-grade optical coatings
  • Useful for thermal imaging and spectroscopy

These properties make ZnSe particularly attractive for systems that require both infrared performance and a broad usable spectral range.
