A device for measuring refractive index and polarisation index of liquid substances.

摘要

1. A device for measuring refractive index and polarization index of liquid substances is equipped with a source of linearly polarized light, a polarimetric tube in the form of a capillary vessel of a determined length, and with an analyser. It is characterised in that the analyser (5), secured at the end of the capillary tube (4), is equipped with a photodetector (6). Another photodetector (7) is located in the path of the radiation component beam (1) reflected from the surface of examined liquid (3). The source of polarised light is secured to slide along the top arc (8) with angular scale. The capillary tube (4) is secured to slide along the opposite bottom arc (9), located at the opposite side of the shared rotation axis of the capillary tube (4) and the source of linearly polarised light.
