UV-enhanced aluminum-coated mirrors are highly suitable for beam deflection (in circular or elliptical shapes) and beam separation (in D-shape) across the ultraviolet spectral range, offering high reflectance across a broad wavelength range. Light is reflected from the metallic coating without introducing chromatic aberration. However, metallic coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. To prevent this, LBTEK’s UV-enhanced aluminum-coated mirrors are coated with a layer of silicon dioxide protection film, isolating the metal coating from direct contact with air and preventing oxidation that could affect optical performance. LBTEK offers UV-enhanced aluminum-coated mirrors in various sizes, including circular, elliptical, and D-shaped options.
LBTEK offers elliptical UV-enhanced aluminum-coated metallic flat mirrors with short axes of 12.7 mm or 25.4 mm. Metallic-coated mirrors are highly suitable for beam deflection in broadband light sources, providing high reflectance across a wide spectral range. However, metallic coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. To address this, LBTEK’s metallic-coated mirrors are coated with a layer of silicon dioxide protection film, isolating the metal coating from direct contact with air and preventing oxidation, which could affect optical performance.
