Reflectivity of gold vs wavelength
WebThe reflectivities of Ag, Au, Cu, and Al were measured at an angle of incidence of 45°, in the wavelength range of 0.40μ to 0.95μ at glass-metal and air-metal interfaces. These reflectivities, together with previously determined values of the absorption coefficient k, were used to calculate the index of refraction n. Samples were prepared by evaporation … WebInfragold-LF MIR-FIR reflectance coating is an electrochemically plated, diffuse, gold-metallic coating which is ideal for use in the MIR-FIR wavelength range. Typical reflectance is …
