We offer the "193nm High Reflective Laser Mirror" for ArF excimer lasers developed by Optoman. Achieving a reflectivity of ">98% @193nm" with IBS coating. To realize high reflectivity in the ultraviolet wavelength range, it is essential to effectively control scattering and absorption losses. For UV laser users, mirror degradation is a significant issue. The manufacturer has focused on surface quality and optimized coating technology. This technology protects the optical system from UV lasers and extends its lifespan. 【Product Specifications】 ■ Material: UVFS (Corning 7980 0F) ■ Diameter: 25.4mm +0/-0.1mm ■ Thickness: 6.35mm +/-0.1mm ■ Effective Diameter: 22mm ■ Surface Accuracy S1: <λ/10@633nm over any 15mm diameter *For more details, please download the PDF (English version) or feel free to contact us.

Manufacturer: OPTOMAN (Lithuania) OPTOMAN's lenses are coated with IBS and optimized for high-power laser applications. This means they can be used for intra-cavity and multi-kW CW lasers, as well as ultra-fast pulse applications. To achieve this performance, optimized low-absorption fused silica is used. There is no thermal shift during use. The robust, wear-resistant coating is close to bulk and provides fatigue-free, environmentally independent performance. The state-of-the-art IBS coating technology enables excellent features such as high damage thresholds, low absorption, and low scattering. OPTOMAN offers custom solutions for wavelength, reflection, transmission rate, SP polarization, incident angle, branching ratio, damage threshold, and more.
