Detailed

Custom ZnSe Zinc Selenide Infrared Optical Window For CO₂ Laser & Infrared Detection

 
Felix Glass ZnSe selenide infrared window is made of high-purity zinc selenide crystal, featuring ultra-wide infrared transmission range from 0.6μm to 18μm, with extremely low absorption loss at 10.6μm CO₂ laser band, which is the core protective window material for industrial CO₂ laser equipment.
 
We provide round, square and rectangular ZnSe blanks with customizable size, thickness and edge chamfer. Double-sided anti-reflection AR coating for infrared band can be deposited to raise infrared transmittance above 95%. The material features stable thermal performance, low thermal expansion coefficient, not easy to deform under long-time laser irradiation.

Standard FAQ

 
1. Why choose ZnSe for CO₂ laser window?
ZnSe has ultra-low absorption at 10.6μm, high infrared transmittance, better thermal stability than other infrared crystals.
2. Can I customize anti-reflection coating for specific infrared wavelength?
Yes, we customize AR coating matched to 2~14μm infrared band according to customer working wavelength.
3. What shapes of ZnSe window can you produce?
Round, square, rectangular and special irregular shapes are all available for OEM customization.
4. What’s the difference between coated and uncoated ZnSe window?
Uncoated ZnSe has around 70% transmittance; IR AR coated one reaches over 95% transmittance, less energy loss.
5. Do you supply small quantity samples for laser equipment R&D test?
We accept 1 piece small sample order and provide complete spectral transmittance test certificate for each batch.
