Special electronic screen reader of spectrometer

Abstract

The invention provides a special electronic screen reader of a spectrometer. The device comprises a base, a washer, a brightness adjusting knob, a power supply interface, an AV video interface, an adapter box, a data line, a lifting sleeve, a fixing main shaft, a vertical telescopic shaft, a focusing knob, a cantilever fixing knob, a cantilever arm, an electronic microscope camera, an LED lamp, acamera lens, a strong magnet, a camera fixing knob and a power adapter. The effect of the special electronic screen reader is that the electronic microscope camera is fixed above the scale area of thespectrometer through the magnetic adsorption type metal lifting support, and the scale of the spectrometer is photographed by the electronic microscope camera and is output to the screen through theAV interface for display. The lifting support is adsorbed on the cursor plate of the spectrometer through the magnet, and the position and height can be adjusted. The camera focal length can be adjusted and the LED lamp with adjustable brightness can provide lighting under the dark room condition, so that the calibrating value of the spectrometer can be read easily.

Description

technical field [0001] The invention relates to a physical experiment teaching auxiliary device, in particular to a special electronic screen reader for a spectrometer. Background technique [0002] The spectrometer is one of the necessary and commonly used instruments in the teaching of physics experiments. During the experiment, it is necessary to read the angle of the telescope on the dial. Due to the need for high measurement accuracy, the scales on the dial are very dense, and In terms of structure, the vernier reading method of separating the main ruler and the auxiliary ruler is adopted. The reading process is relatively complicated, which is also the key and difficult point of teaching, and needs to be explained in detail. Spectrometer experiments are usually carried out in a dark room, and the scale is difficult to identify without lighting, and improper lighting will affect the experimental results. Manufacturers generally equip optical magnifiers with lighting so...
