Product Overview
High-Efficiency ZnSe AR Coating at 10.6um for CO2 Laser Optics
Optimizing throughput and managing thermal runaway are critical challenges in high-power CO2 laser systems and thermal imaging applications. The iroptical high-efficiency anti-reflective (AR) coating on Zinc Selenide (ZnSe) substrate is engineered specifically for the 10.6um wavelength, delivering exceptional transmission while minimizing parasitic reflections. By choosing our precision optical coatings, R&D engineers can significantly enhance system efficiency, lower thermal distortion, and extend the lifespan of critical optical assemblies.
