Description

Technical Field

[0001] This utility model relates to the field of microscope technology, and in particular to an automatic light-blocking device and microscope system. Background Technology

[0002] When using the fluorescence channel in a microscope, the LEDs need to be shielded to avoid interference from light reflected back from below the microscope. Operators typically use a plastic cover to shield the LEDs by hand, which is unsuitable for automated microscope systems. Furthermore, some fully automated microscopes achieve this function by adding a conventional motor module, but these modules are too bulky and expensive. Therefore, it is necessary to develop a compact and inexpensive automatic light-shielding device. Summary of the Invention
