A plurality of magnets is provided in an illumination prism carrier of a transmitted light refractometer and a corresponding plurality of magnets is provided in a sample prism housing of the refractometer to align a light exit surface of the illumination prism relative to a sample surface of the sample prism and urge the optical surfaces together in an even and uniform manner. The magnets replace mechanical biasing arrangements for positioning the optical surfaces and function to consistently reproduce a measurement optical path in the instrument for improved accuracy and repeatability of measurements.
