The experimental results show that compared with Brewster angle method, the grazing method and minimum deviation angle method are more accurate in measuring the refractive index.This paper provides an experimental method for accurate measurement of refractive index of prism.Jinbo TAN...
We measured the top angle of triangular prism, and the different angles of minimum deviation according to different monochromatic light traveling through the prism, then calculated the refractive index of prism. In the visible light area, the refractive index depending on light wavelength was in ...
In addition, modern digital refractometers automatically control the temperature in the prism/sample boundary to enhance the accuracy of the measurement. Measuring Refractive Index / What Does a Refractometer Measure? A digital refractometer measures the refractive index or relate...

When using a prism with precisely known opening angle, a precise goniometer (angle measuring instruments) and a carefully chosen method for determining the refractive index of the surrounding air, a rather high precision of the order of 10−6 for the refractive index can be achieved. There ...
A test specimen of any size may be used as long as it conveniently fits on the face of the fixed half of the refractometer prism. The surface of the specimen in contact with the prism must be flat and polished. The test is carried out by placing a specimen in contact with the prism ...
