The gold-plated mirror can provide the highest reflectivity and the highest environmental stability for the infrared (IR) wavelength, which can reach 98-99% in the entire infrared spectrum. Gold-plated (Au) optical mirrors are ideal for applications in the wavelength range of 750 – 1500 nm (more than 12 um). We can customize and manufacture gold-plated mirrors to meet the reflectivity and environmental stability requirements of specific optical mirror applications.
The silver-plated mirror can provide excellent reflectivity, which can reach 95-99% even in the far infrared spectrum, and from 450nm to more than 12 μ The reflectivity of m can reach more than 95%. However, silver-plated (Ag) mirrors may not be ideal for some applications because their reflectivity in the blue and ultraviolet spectral areas may be less than 90%. Fortunately, silver-plated mirrors can be customized to meet the reflectivity and transmittance requirements of your specific optical applications, and protective coatings can be provided to help protect silver-plated mirrors from discoloration.
