Abstract
The invention provides a spectrometer demonstration experimental instrument comprising a metal plate, a laser, an object stage and a dial. The laser penetrates from the outer side of the metal plate into the metal plate, the object stage is arranged in the center of the bottom of the metal plate, and the dial is engraved on the inner side of the metal plate and used for angle measuring. The laser emits a beam of parallel light which directly penetrates through the center of the object stage and forms a laser light spot on the dial. The reading value a1 of the position where the laser light spot is located on the dial is recorded. A prism, a grating and other optical devices are arranged on the object stage. The parallel light emitted by the laser forms one or more laser light spots on the dial after passing the optical devices. The reading value a2 of the position where a certain laser light spot is located on the dial is recorded. The deflection angle of the light is a2-a1. According to the instrument, the metal plate can be used as a container, solutions with different refractive indexes are poured into the container, and the deflection angle of the light changes correspondingly due to the fact that the relative refractive indexes of the optical devices on the object stage are changed. Fine suspended particles are added to the solutions, and a part of laser is scattered by means of the particles to achieve visualization of a light path.
Description
Technical field
The present invention relates to a kind of spectrometer demonstration test instrument, be mainly used in large, special secondary school universities and colleges and physics experiments of high school teaching.
Background technology
At present, the spectrometer experiment instrument that colleges and universities adopt is JJY1 type spectrometer.Spectrometer is the instrument at Accurate Measurement light deflection angle, can be for the refractive index of measuring material, the spectrum of light source, in the research of the research of spectroscopy, material behavior, polarized light, prism characteristic, Grating Properties, all be widely used.This teaching experimental device price that school adopts at present, parts easily damage, and need frequent M R, and adjustment process are loaded down with trivial details, can't realize measuring in solution.In senior middle school, due to complicated, the difficult operation of experimental apparatus, generally seldom offer this experiment.
