    Protective Windows act as the first line of defense for the more expensive optical components in high-energy laser systems. Positioned as the final optical element they shield critical optics from debris, fumes, and environment in general ensuring system uptime while withstanding laser powers of multiple kilowatts.​

    Our optical windows are precision-engineered to deliver superior performance and reliability in demanding laser applications. Designed with high-quality substrates and advanced coatings, these windows offer minimized thermal effects, low scattering, and high Laser-Induced Damage Threshold (LIDT), ensuring long lifetimes and reducing the need for frequent replacements.​

    Anti-Reflection (AR) Coatings enhance system throughput by minimizing reflective losses and backscattering, preventing ghost images, and maintaining optimal spectral performance. Each coating is designed by our experienced engineers considering specific requirements of your application ensuring consistent, long-lasting efficiency.
