Abstract

Three geometrically different diffuse reflectance accessories were compared in terms of the throughput and ease of operation. The capability to discriminate the specular component against the diffuse reflectance component was investigated by the use of high refractive index samples. It was found that in all three accessories the specular as well as the diffuse reflectance components have similar reflection and polarization characteristics and that the specular component is primarily sample-dependent rather than accessory-dependent.
