Bearing structure of miniature zoom microscope

Abstract

The bearing structure of the miniature zoom microscope comprises a zoom device, a main body and a positioning device which are sequentially connected from top to bottom, the zoom device is slidably connected to the main body, the positioning device comprises an objective lens base and a relay lens switching base which are magnetically connected, the objective lens base is connected with the main body, and the zoom device, the main body, the objective lens base and the relay lens switching base are located on the same light path; a light source fixing device is arranged on the main body, and a light source facing the light path is formed on the light source fixing device; the main body is also provided with an auxiliary clamp; compared with the prior art, the internal design of the light source fixing device ensures that the light emitted by the light source can be propagated in the structural member according to a preset light path so as to realize an expected imaging effect, and the auxiliary fixing clamp ensures that the bearing main body can ensure the relative horizontal and vertical installation of the whole system in the biological experiment process, so that the imaging effect is improved. And the complexity of system adjustment during an experiment is reduced.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a bearing structure of a miniature zoom microscope. Background technique [0002] Exploring how neural activity in an organism creates different brain functions and the behaviors that result from those functions is one of the central questions in neuroscience, which requires recording neural activity during an organism's behavior in order to This determines the causal relationship between neural activity and biological behavioral processes. [0003] Today, the commonly used methods for in vivo brain imaging are mainly calcium indicators combined with fluorescence microscopy imaging. Changes in the frequency of cellular action potentials can be represented by changes in calcium ion concentration. After binding calcium indicators to generate fluorescent proteins and excitation to generate fluorescence, these fluorescent signals can be collected for imaging. [0004] However, ...

Problems solved by technology

[0004] However, due to the living structure of the experimental animals, the experimental animals will move freely during the observation process, and it is difficult to adjust the position of the existing microscope, thus affecting the observation effect
