Concave mirrors can be used for beam focusing, collimation, or light collection, offering high reflectivity within their operational range. LBTEK dielectric-coated concave mirrors feature a dielectric reflective film on the concave surface and a frosted backside, achieving an average reflectivity of up to 99% across the working wavelength range. In addition to standard products, LBTEK can customize concave mirrors with different sizes, focal lengths, and working wavelengths. For inquiries, please contact LBTEK Technical Support.
