Optical- and semiconductor-grade Zinc Selenide (ZnSe, CAS 1315-09-9), ≥99.99%, supplied wholesale by Zyntex. Infrared material for CO2 laser optics, IR windows, quantum dots and thin films. CoA and SDS with every lot.
Zinc selenide (ZnSe) is a light yellow solid that transmits light over an exceptionally wide range, from about 0.5 to 22 µm. It has a band gap of about 2.7 eV and very low absorption at 10.6 µm, the wavelength of CO2 lasers.
Optics producers grow dense ZnSe by chemical vapor deposition and machine it into lenses, windows and beam splitters for CO2 laser cutting and welding systems, thermal imaging and FTIR spectroscopy. In infrared optics, Germanium Metal is a common alternative with different transmission properties.
As a II-VI semiconductor, zinc selenide is used in quantum dot shells, phosphors and research on blue-green emitters. High-purity powder serves as an evaporation source and sintering material. For related selenides and raw materials, see Selenium, Tin selenide and Bismuth selenide.

⚠️ Safety & Handling: Toxic if swallowed or inhaled, may damage organs through prolonged exposure, and is very toxic to aquatic life. Contact with acids releases highly toxic hydrogen selenide gas. Avoid dust formation, use local exhaust ventilation, and wear gloves, eye protection and respiratory protection. Store in a dry place away from acids. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Why is ZnSe used for CO2 laser optics?
It has very low absorption at 10.6 µm and transmits visible light, which makes alignment with visible lasers easy.
Do you supply finished optics?
Powder and granules are the standard forms. Finished windows and lenses can be quoted on request with your specifications.
How can I get a price and documents?
