LBTEK metallic-coated mirrors are highly suitable for beam deflection in broadband light sources, offering high reflectance across a wide spectral range. The mid-infrared enhanced gold-coated mirrors have superior reflectance compared to standard gold-coated mirrors in the 2.0 μm–20.0 μm range, providing an average reflectance of 98%. 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.
LBTEK offers five types of metallic-coated mirrors: gold-coated, mid-infrared enhanced gold-coated, silver-coated, aluminum-coated, and UV-enhanced aluminum-coated.
LBTEK offers Ø25.4 mm mid-infrared enhanced gold-coated flat mirrors in both single and 10-piece packs. The mid-infrared enhanced gold-coated mirrors provide superior reflectance compared to standard gold-coated mirrors in the 2.0 μm–20.0 μm range, with an average reflectance of 98%. Metallic coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. To prevent 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.
