AR Coated Windows

OPTOMAN’s AR Coated Windows are designed to maximize transmission and protect laser systems by minimizing reflection losses and backscatter. While they may appear simple, laser windows play a critical role in maintaining system efficiency, stability, and safety - especially in high-power or sensitive optical setups.

Coated using advanced Ion Beam Sputtering (IBS) technology, these windows deliver high transmittance, excellent spectral performance, and a high laser-induced damage threshold (LIDT). Anti-Reflection (AR) coatings are applied to increase system throughput and reduce the risk of ghost images caused by back reflections. They are engineered to withstand temperature fluctuations, humidity, and long-term optical fatigue, ensuring reliable performance in demanding environments.

Need a window that will separate part of your optical setup, or protect your laser system from back reflections? OPTOMAN’s AR Coated Windows offer the protection you can rely on, while ensuring maximum light transmission and minimal losses. Explore the options below.
