Abstract:

The theory for the regular normal transmittance of a rough dielectric interface is compared with experimental results. Relative regular transmission data from a very novel experiment involving variation of interface refractive index ratio and root-mean-square rms roughness at a single wavelength are found to be in excellent agreement with the theoretical transmittance relation for a rough dielectric interface having a Gaussian distribution of surface heights. Also, absolute spectral transmission measurements for rock-salt NaCl windows roughened on both faces are found to be in good agreement with the regular transmittance theory at wavelengths where absorption and surface scattering are negligible.
