Apparatus for measuring specular reflectance of a sample

摘要

An accessory for a spectrometer for carrying out measurements of specular reflectance of a sample. The accessory is designed so that all components are located in a housing and the sample is located horizontally on a top-plate of the housing with the components disposed below the plane of that plate. The accessory comprises four reflectors which direct the incoming beam to the sample. The reflected light from the sample is detected by a detector located inside the housing.
