UV-enhanced aluminum-coated concave mirrors are highly suitable for beam focusing or collimation, as well as beam collection in a broad ultraviolet spectral range, offering high reflectivity across a wide spectrum. The reflection of the beam occurs on the metal-coated surface, eliminating chromatic aberration. However, metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. LBTEK's UV-enhanced aluminum-coated mirrors feature a protective silicon dioxide layer on the surface to isolate the metal coating from direct contact with air, preventing oxidation and preserving optical performance. 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 that LBTEK provides high-quality lens products at reasonable prices.
