Description
High Purity Laser Grade CVD ZnSe for CO₂ Laser Applications
Our laser grade CVD ZnSe optical components are manufactured from low-absorption CVD zinc selenide material, optimized exclusively for high-power CO₂ laser equipment. Unlike standard IR-grade ZnSe for thermal imaging, this laser substrate keeps thermal loss minimal under continuous laser power. Compare with our IR-grade ZnSe infrared domes for thermal imaging systems.
Core Product Range: Dome, Window & Plano-Convex Lens
- Hemispherical & flanged CVD ZnSe dome for laser rangefinder front optics
- Flat thick ZnSe output window for industrial laser cutting machines
- Plano-convex ZnSe focusing lens with precise surface figure
All shapes support custom outer diameter, wall thickness and edge machining. Read our full material selection blog to pick the right substrate grade.
Key Advantages of Laser Grade CVD ZnSe Substrate
- Ultra-low bulk absorption at 10.6μm CO₂ laser wavelength
- High laser-induced damage threshold (LIDT) for continuous high power
- Broad 0.6–16μm infrared transmission for multi-band laser systems
- Strict raw material sorting, separated fully from IR imaging grade ZnSe
- Precision polishing to λ/4 surface figure with tight wall thickness uniformity
Optical Coating Options for Laser ZnSe Optics
We provide single-side and double-side AR anti-reflection coating tuned for 10.6μm CO₂ laser. DLC hard coating is available to improve scratch resistance in industrial workshop environments. Coating parameters can be fully customized per your laser system specs. See coating technical details in our engineering design article.

Frequently Asked Questions for Laser Grade CVD ZnSe Optics
1. What is the difference between laser grade CVD ZnSe and IR imaging grade ZnSe?
Laser grade ZnSe features ultra-low absorption at 10.6μm to withstand high CO₂ laser power, while IR-grade ZnSe prioritizes wide infrared transmission for thermal cameras. View IR-grade dome product.
2. Can you produce flanged CVD ZnSe domes for laser rangefinders?
Yes, we machine flanged edges on laser grade ZnSe hemispherical domes with tight dimensional tolerance. Check the design specs in our engineering blog.
3. Do you offer AR coating optimized for 10.6μm CO₂ laser?
Double-sided anti-reflection coating tuned for 10.6μm is our standard option for laser windows and lenses. Custom broadband coating is also available.
