Material & Grade Overview
We adopt laser‑grade CVD Zinc Selenide (ZnSe) featuring ultra‑low bulk absorption, broad transmission from 0.5μm‑22μm, suitable for mid‑infrared application scenarios. Material substrate does not equal final performance grade. Please inform us of your working wavelength, laser power level and coating requirements to avoid improper material selection.

Coating Selection Guide
AR coating at 10.6 μm minimizes surface reflection and reduces energy loss for CO₂ laser operation. Broadband IR‑AR coating suits multi‑spectral infrared systems. All coatings are designed according to your incident‑angle and spectral requirements. Learn more about infrared optical coating technology.
