Abstract

The invention discloses a prism refractive index measurement system, comprising a light source, a measurement mechanism and a collimating member. The measurement mechanism comprises a casing, a gyroscope sensor, a clock module, a central processing module and a display module; the gyroscope sensor, the clock module, the central The processing modules are all arranged inside the casing, and the outer casing is provided with a measuring wall; the gyroscope sensor, the clock module, and the display module are electrically connected to the central processing module, which replaces the tedious measurement of the prism refraction angle and the minimum deflection angle by the spectrometer, and saves the The manual calculation process is simple and fast; the invention discloses a prism refractive index measurement method, which uses a gyroscope and a central processing module to calculate the prism refraction angle and the minimum deflection angle, and uses the central processing module to calculate the refractive index, Thus, the prism-related angle measurement and the calculation of 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...
