AT Optical Instruments Co., Ltd.

193 nm ≤ λ ≤ 400 nm

Narrowband anti-reflection coatings—commonly known as “V-coatings”—are designed to minimize surface reflectance at a specific center wavelength. They provide excellent durability and high laser damage resistance, making them well-suited for demanding optical and laser applications.

193 nm ≤ λ ≤ 400 nm

AT Optics’ Ultraviolet RMAX high-reflection coatings are engineered for outstanding reflectivity across the UV spectrum. Featuring advanced all-dielectric thin-film designs, they offer extremely low absorption and scattering losses, ensuring stable and reliable performance in demanding UV applications.

193 nm ≤ λ ≤ 400 nm

AT Optics’ partial reflection coatings enable precise beam splitting and output coupling with stable performance. Optimized for high-power use, they offer strong resistance to excimer gases and are ideal for excimer and intracavity laser systems.

193 nm ≤ λ ≤ 400 nm

AT Optics offers polarizing and non-polarizing beamsplitter coatings for precise control of monochromatic light. Polarizing designs efficiently separate S and P components with high extinction ratios, while non-polarizing coatings preserve polarization and ensure accurate beam splitting. Optimized for wavelength and angle of incidence, all coatings deliver stable performance and excellent resistance to laser-induced damage in demanding optical and laser systems.
