Description

Electronic screen readout for spectrometers

technical field

The invention relates to a physical experiment teaching auxiliary device, in particular to a special electronic screen reader for a spectrometer.

Background technique

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 sources. But this kind of magnifying glass can only be watched by the experimenter himself. When the teacher is giving a lecture, facing dozens or even dozens of students, he has to explain the reading method. At this time, the original optical magnifying glass cannot be watched by many people at the same time, and cannot meet the needs up. There is currently no technology on the market specifically designed to address spectrometer readings for simultaneous viewing by multiple people.

In view of the above existing problems, the design idea of a special electronic screen reader for spectrometer of the present invention is to solve the problem that students cannot see the details of the specific reading during the process of explaining the reading of the spectrometer in the physics experiment teaching.
