Abstract

The optical constants n and k of evaporated platinum films on glass substrates have been measured in the spectral region 4500Å–7500Å. The reflectance R_m of gold and platinum films on a potassium tantalate (KTaO₃) substrate has been measured from the substrate side and found to be somewhat lower than the calculated values. This discrepancy may be explained by relatively small alternations in n and/or k of the metal film or by scatter at the KTaO₃–metal interface.
