Abstract

The invention discloses a system used for measuring refractive index of a prism. The system comprises a light source, a measuring mechanism and a collimation part, wherein the measuring mechanism comprises a shell, a gyroscope sensor, a clock module, a central processing module and a display module; the gyroscope sensor, the clock module and the central processing module are respectively arrangedinside the shell, and the shell is provided with a measurement wall; the gyroscope sensor, the clock module and the display module are electrically connected with the central processing module, tedious measurement of a spectrometer on a refraction angle and a minimum deviation angle of the prism is replaced, and a manual computation process is eliminated, so that a measurement process is simple and quick. The invention discloses a method used for measuring the refractive index of the prism. A gyroscope and the central processing module are utilized for calculating the refraction angle and theminimum deviation angle of the prism, and the central processing module is utilized for calculating the refractive index, so that measurement on related angles of the prism and calculation on the refractive index are conveniently realized.

Description

technical field [0001] The invention relates to the technical field of measuring the refractive index of prism glass, in particular to a method and a measuring system for measuring the refractive index of a prism. Background technique [0002] Currently, the refractive index of a prism is measured using a spectrometer. A spectrometer is a device for measuring angles, mainly composed of four parts, collimator, telescope, stage and reading device. When using a spectrometer to measure the refractive index of a prism, it must be adjusted to infinity through the "telescope; adjust the optical axis of the telescope to be perpendicular to the central axis of the spectrometer; adjust the normal line of the stage to be parallel to the central axis of the spectrometer; After complex adjustments such as adjusting the optical axis of the collimator to be perpendicular to the central axis of the spectrometer, the relative measurement of the prism angle and the minimum deflection angle c...
