400 nm ≤ λ ≤ 532nm

AT Optics’ narrowband anti-reflection coatings (“V-coatings”) deliver ultra-low reflectance below 0.25% at the target wavelength under normal incidence. Optimized for laser applications, they outperform single-layer AR coatings in precision and efficiency. Engineered with advanced materials, they provide enhanced power handling and durability for high-power laser systems.

425 nm ≤ λ ≤ 675 nm

AT Optics’ broadband anti-reflection coatings deliver low reflectance across a wide spectral range. With reduced sensitivity to angle of incidence compared to V-coatings, they are ideal for high-NA optics, steeply curved lenses, and systems where incidence angles vary.

425 nm ≤ λ ≤ 650 nm

AT Optics’ broadband RMAX high-reflection coatings deliver outstanding reflectivity across a wide spectral range. Built with advanced all-dielectric thin-film designs, they offer ultra-low absorption and scattering losses for consistent performance. With reduced sensitivity to angle of incidence compared to laser-line coatings, they are ideal for high-NA mirrors, steep curvatures, and dynamic optical systems.

400 nm ≤ λ < 633nm

AT Optics’ laser-line RMAX high-reflection coatings provide peak reflectivity at targeted wavelengths with minimal absorption and scattering losses. Engineered with advanced materials for high-power applications, they offer enhanced durability and superior power handling compared to standard RMAX coatings.

400 nm ≤ λ ≤ 700 nm

AT Optics’ partial reflection coatings deliver precise beam splitting and output coupling with controlled reflectance ratios. Designed for stable optical performance, they efficiently manage monochromatic light in demanding systems.Engineered with advanced materials, high-power variants offer enhanced durability and superior power handling for laser applications.

400 nm ≤ λ ≤ 633 nm

AT Optics’ polarizing cube beamsplitter coatings are engineered within precision-cemented right-angle prisms to separate unpolarized light into S and P components with extinction ratios over 1000:1. They produce two orthogonally polarized beams exiting at 90°, and can also be used for efficient beam combining in advanced optical systems.

425 nm ≤ λ ≤ 675 nm

AT Optics’ non-polarizing broadband cube beamsplitter coatings are formed between precision-cemented right-angle prisms using advanced metal-dielectric thin-film designs. They divide polychromatic light into reflected and transmitted beams at a controlled 45/45 ± 5% ratio, while preserving polarization for stable and consistent optical performance.
