Microscope stage and automatic demonstration system for teaching and exhibition

Abstract

The invention discloses a microscope stage for teaching and exhibition. The microscope stage comprises a sample disc, a cover plate, elastic elements, bolts and nuts, a plurality of slide grooves used for storing slides are formed in the sample disc, each slide groove corresponds to a plurality of bolts, nuts and at least one elastic element, the cover plate covers the slide grooves, and the bolts sequentially penetrate through the cover plate and the sample disc and then are connected with the nuts in a threaded mode, so that the slides are fixed in the slide grooves; the elastic elements abut against the position between the cover plate and the sample disc, and when the slides are installed, the nuts and the elastic elements are matched to adjust the heights of the slides, so that pre-adjustment of focal lengths of the slides is achieved, the slides do not need to be subjected to focusing one by one when the sample disc is rotated for slide replacing, and demonstration is convenient. The invention further discloses an automatic demonstration system, automatic slide replacing of the microscope stage can be achieved, and when the slides are replaced, slide images and commentary information are correspondingly displayed, and the microscope stage and the automatic demonstration system are suitable for teaching and exhibition.

Description

technical field [0001] The invention relates to a microscope, in particular to a microscope stage for display and teaching and an automatic demonstration system thereof. Background technique [0002] Due to the fact that there are very few microscopes specially used for demonstration and teaching, in order to facilitate people, especially children, to learn and understand the knowledge of microscopes and some cells, most of the functions of existing microscopes are often shielded, such as blocking objective lens switching, condenser lens, etc. Adjustment, illumination adjustment, stage displacement, coarse focus or even focus fine-tuning, eyepiece adjustment, etc. In the end, almost only the adjustment of the interpupillary distance is left. Usually, each microscope can only observe one sample. Since it is impossible to ensure that the condenser, lighting, aperture diaphragm and field diaphragm are in a matching state, the contrast of the seen image is low, which directly af...

AI Technical Summary

Problems solved by technology

Since the condenser, lighting, aperture diaphragm and field diaphragm cannot be guaranteed to be in a matching state, the contrast of the seen image is low, which directly affects the display and viewing effect

[0003] In order to facilitate the demonstration, a special digital optical microscope for display has been developed in the prior art. The microscope is provided with multiple glass slides at the stage. During the demonstration, the stage needs to be moved, and a certain slide on the stage needs to be moved. Align the objective lens, and then when the microscope observes a certain slide, the demonstrator needs to adjust the focal length of the slide, that is, move the stage once, adjust the focus of the slide once, and the operation is complicated
