🟡 ：What is a ZnSe Window?
A ZnSe window (Zinc Selenide optical window) is a high-performance infrared optical component widely used in CO₂ laser systems operating at 10.6 μm wavelength.
It is one of the most important materials for:
• Industrial laser cutting machines
• Laser welding systems
• Thermal imaging equipment
• Infrared sensing systems
Compared to standard optical glass, ZnSe provides:
• Much higher infrared transmittance
• Lower absorption in CO₂ laser wavelength
• Better thermal stability under laser exposure
⸻
🔷 ：Key Features of Our ZnSe Window
• High transmission in infrared spectrum (especially 10.6 μm CO₂ laser)
• Low optical distortion for laser beam accuracy
• High laser damage threshold
• Excellent surface quality polishing (low scattering)
• Stable AR coating adhesion
• Custom thickness and diameter available
⸻
🧪 ：Material Performance
Our ZnSe optical material is optimized for:
• CO₂ laser systems (10.6 μm wavelength)
• High-power infrared laser environments
• Industrial-grade optical stability
• Long-term thermal resistance under continuous laser operation
