AR Coated Fused Silica Laser Protection Windows
AR (Anti-Reflective) Coated Fused Silica Laser Protection Windows are high-performance optical components designed to maximize light transmission while minimizing surface reflections in laser systems. Made from ultra-pure fused silica (SiO₂), these windows feature precision anti-reflective coatings tailored to specific wavelengths, ensuring optimal performance in demanding laser applications.
Key Features & Benefits
✔ Ultra-Low Reflectivity – <0.25% per surface at designed wavelengths, maximizing transmission efficiency.
✔ High Laser Damage Threshold – Withstands >10 J/cm² (1064nm, 10ns pulse) for high-power laser systems.
✔ Broadband & Wavelength-Specific Options – Coatings optimized for UV (193-355nm), Visible (400-700nm), or IR (1064-1550nm) ranges.
✔ Exceptional Thermal & Chemical Stability – Operates from -200°C to +1200°C, resistant to acids and plasma.
✔ Precision Polished Surfaces – λ/10 flatness, <5-10 scratch-dig for minimal wavefront distortion.
Applications
● High-Power Laser Systems – CO₂, Nd:YAG, excimer, and fiber laser protection.
● Semiconductor Lithography – Stepper lenses, DUV/EUV optical modules.
● Medical & Aesthetic Lasers – Surgical lasers, skin treatment systems.
● Defense & Lidar – Laser rangefinders, IR countermeasures, beam delivery.
● Scientific Research – Spectroscopy, ultrafast lasers, quantum optics.
