Description

Technical Field

[0001] The invention relates to the technical field of microscope optical accessories, and in particular to a shading device and a shading control system for a fluorescence microscope. Background Art

[0002] Fluorescence microscope: Fluorescence microscope uses ultraviolet light as a light source to illuminate the object being inspected, causing it to emit fluorescence, and then observe the shape and location of the object under the microscope. Fluorescence microscopes are used to study the absorption, transportation, distribution and location of substances in cells. Some substances in cells, such as chlorophyll, can fluoresce after being irradiated with ultraviolet light; some other substances cannot fluoresce by themselves, but if they are stained with fluorescent dyes or fluorescent antibodies, they can also fluoresce after being irradiated with ultraviolet light. Fluorescence microscopes are one of the tools for qualitative and quantitative research on such substances. At present, the fluorescent lamps of most fluorescent microscopes are manually set. When using a fluorescent microscope for somatic cell nuclear transplantation, since both hands are required to operate the micromanipulator, if there is time and one hand to move the fluorescent lamp baffle, it will affect the experiment.
