ZnSe CO₂ protective window| Sapphire Hard Coated ZnSe Optic

Core Application Scenarios

 

CO₂ Laser Cutter | Engraver | Marker | Lab IR Equipment | Medical & Aerospace Optics

 

Founded in 2006, full-chain ZnSe factory serving 120+ global laser brands, our ZnSe CO2 protective window is core protective part for laser machines. This sapphire coated ZnSe lens matches complete CO2 laser cutting lens set, crafted as premium high transmittance ZnSe lens. We stock standard 2/2.5/3 inch ZnSe window and produce custom OEM laser protective component for worldwide buyers.

 

Ordinary AR ZnSe fails in 30-90 days from slag damage. Our sapphire coating keeps 95% fixed IR transmittance for 12+ months nonstop work, cutting your maintenance cost by 62.7% (US client saved $12,000 yearly).
