Description

Technical Field

[0001] The utility model relates to the technical field of optical detection auxiliary equipment, in particular to an automatic filter switching device. Background Art

[0002] In the optical inspection device for samples, a filter is typically placed directly below the camera to ensure that the camera light can accurately pass through the filter during acquisition. When testing different samples or comparing the same sample under different inspection conditions, filters of different wavelengths may need to be replaced for each test.

When a different filter is needed, the original filter needs to be removed from the filter holder and replaced with a new filter, resulting in low detection efficiency and inconvenient operation. There is a lack of an automatic switching device that can quickly and automatically change filters of multiple bands. Utility Model Content
