The entry 1 and entry 3 in the table below illustrates the change of refractive index with the change of .
For high accuracy in commercial refractometry, refractometers should be used more strictly as comparison instruments and series of standard samples with known refractivities over a range of room temperatures should be available for frequent check measurements. Tests for various mechanical and optical defects are necessary and compensators should be examined for their .
A refractometer is a scientific instrument used to measure the refractive index of different materials – a value indicating how much the phase velocity of light is smaller compared with propagation in vacuum.
