Abstract

The invention discloses a refractive index measuring instrument for transparent material with the Brewster angle, comprising an upright post and a one-fourth circular arc guide rail taking the upright post as the radius. The guide rail is provided with a laser emitter which can slide along the circular arc direction of the guide rail and is opposite to the direction of the center of a circle of the circular arc guide rail, and an objective table is arranged at the center position of the circle of the circular arc guide rail; the upright post is vertically provided with a scale beam below which a polarization film strip is arranged, and a photoelectric sensor is arranged between the polarization film strip and the scale beam and connected with a digital display indicator. The method simplifies a traditional complex refractive index detecting method, can conveniently and simply confirm the components of the transparent material, can accurately measure the refractive index when the three-dimensional surface of the transparent material is not regular without polishing the surface, and can measure the refractive index only by finding a small reflecting surface on a measured object without damaging original ore.

Description

technical field [0001] The invention relates to a transparent material refractive index measuring device, in particular to a Brewster angle transparent material refractive index measuring instrument. Background technique [0002] There are many existing refractive index measurement technologies. When measuring the refractive index (transparent plastic, plexiglass, glass), the detection method of the refractive index is through a very complicated method, which requires a Michelson interferometer, and sometimes the surface of the material needs to be ground Obtaining a regular three-dimensional surface to measure the refractive index requires a certain degree of complexity in the detection operation. [0003] The composition of transparent materials can sometimes be visually inspected, experienced people can see it at a glance, and can also be carefully measured by chemical methods. Seeing with eyes requires a certain amount of experience, and using chemical methods requires ...
