Metal Film Concave Reflectors, no Hole CM10-F100-AU-MIR

Metal Film Concave Reflectors, no Hole — Model CM10-F100-AU-MIR

Operating wavelength 2.0 μm-20.0 μm, focal length -100 mm, Ø25.4 mm, substrate UVFS.

Product Description

• Optical Material: UVFS
• Available in Versions with and without Through Holes
• Applications: Beam focusing, Collimation, Collection, and Imaging

Metal-coated concave mirrors are highly suitable for beam focusing or collimation, beam collection, and other applications with broadband light sources, offering high reflectivity across a wide spectral range. The reflection of light beams on the metal-coated surface does not introduce chromatic aberration. However, metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. LBTEK's gold-coated mirrors feature a layer of silicon dioxide protective coating on the surface to isolate the metal coating from direct contact with air, preventing oxidation and maintaining optical performance. LBTEK offers gold-coated concave mirrors both with and without off-axis holes. All mirrors undergo precision machining and strict quality control to ensure high-quality products for users.

• Substrate Material: UVFS
• Operating Wavelength: 2.0 μm-20.0 μm
• Silicon Dioxide Protective Layer
• Beam Focusing, Collimation, Collection and Imaging

The gold-coated concave mirrors provided by LBTEK utilize mid-infrared enhanced gold coatings, which offer higher reflectivity in the 2 μm-20 μm range compared to standard gold-coated mirrors, with an average reflectivity exceeding 98%. The mirrors employ UV-grade fused silica as the substrate material, ensuring superior thermal stability. A protective silicon dioxide coating is applied to the surface to isolate the metal coating from direct contact with air, preventing oxidation that could compromise optical performance.
