Product Description

l Optical Material: Borofloat Glass

l Silicon Dioxide Protective Layer

l Operating Wavelength: 480 nm-20 μm

l Beam Focusing, Collimation, Collection, and Imaging

     Metal-coated concave mirrors are highly suitable for beam focusing or collimation of broadband light sources and beam collection, offering high reflectivity across a wide spectral range. The reflection of light beams occurs on the metal-coated surface, which does not introduce chromatic aberration. However, metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. Tuniu's metal-coated mirrors feature a protective silicon dioxide layer on the surface to prevent direct contact between the metal coating and air. Although the protective layer can prevent silver oxidation, silver-coated mirrors are still not suitable for use in high-humidity environments. They must be used and stored in room-temperature conditions with minimal humidity. Tuniu offers three types of metal-coated mirrors: aluminum-coated, silver-coated, and gold-coated. All our mirrors undergo precision processing and strict quality control to ensure that Tuniu provides high-quality lens products at reasonable prices. For customized metal-coated mirror requests, please contact Tuniu technical support.

Metal-coated Concave Mirrors, Silver Coating: 480 nm-20.0 μm

     Tuniu offers Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm silver-coated metal concave mirrors. Metal-coated concave mirrors are highly suitable for beam focusing or collimation of broadband light sources and beam collection, providing high reflectivity across a wide spectral range. The beam reflects off the metal coating surface without introducing chromatic aberration. Metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. Tuniu's metal-coated mirrors feature a layer of silicon dioxide protective coating 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. 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.
