Metal-coated mirrors are highly suitable for deflecting light paths of broadband light sources, offering high reflectivity across a wide spectral range. However, metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. LBTEK's metal-coated mirrors feature a protective layer of silicon dioxide on the surface to isolate the metal coating from direct contact with air. Although the protective layer prevents silver oxidation, silver-coated mirrors still cannot be used in high-humidity environments and must be operated and stored in low-humidity, room-temperature conditions. LBTEK offers three types of metal-coated mirrors: aluminum-coated, silver-coated, and gold-coated. All our mirrors undergo precision manufacturing and strict quality control to ensure LBTEK provides high-quality mirror products at reasonable prices.

LBTEK offers elliptical silver-coated metal plane mirrors with a major axis of 35.9 mm and a minor axis of 25.4 mm. Metal-coated mirrors are highly suitable for deflecting light paths of broadband light sources, as they exhibit high reflectivity across a wide spectral range. Metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. To prevent direct contact between the metal coating and air, LBTEK's metal-coated mirrors are coated with a layer of silicon dioxide protective film. Although the protective layer can prevent silver oxidation, silver-coated mirrors should still not be used in high-humidity environments. They must be used and stored in room-temperature conditions with minimal humidity. When handling silver-coated mirrors, it is recommended to wear latex gloves or finger cots to prevent contamination of the optical surface by oils or residues from fingers. Handle with care, avoiding contact with the mirror surface and edges.
