Selective refractometry of materials involves sensitizing measuring surface of measurement prism before material to be tested is set on measuring surface for refractive index determination

摘要

The method involves setting a material to be tested on the measuring surface of a measurement prism, and illuminating material with light radiated in an angle included in the critical angle of total reflection in the receiving surface to determine refractive index of the material. The measuring surface sensitized based on the material before material is set on measuring surface.
