Problems solved by technology

However, due to the structure of adjusting the stage up and down, due to the low machining accuracy, assembly differences between components, and the aging of the entire lifting system for up and down adjustment, the focus fails after frequent lifting and lowering of the stage. The target object is not clear

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The embodiment of the present invention provides a multi-layer shooting method of a multi-layer shooting method for microscope inspection. First, the marker on the counting plate of the counting pool of the stage is used as the starting position of the shooting focus, and then according to the counting position of the mixed liquid in the microscope inspection Switch the liquid level difference of each target in the pool, adjust the objective lens with different optical lengths, make the lens of the camera combine with different objective lenses, focus on different layers of the mixed liqui...

Abstract

The invention relates to a multi-layer photographing method and photographing system for microscopic examination. The system comprises a rack, a stage, an objective lens group and a camera. The objective lens group comprises two or more objective lenses of different optical lengths and is rotatably mounted on the rack by switching the objective lenses. The stage and the camera are respectively mounted on the rack right under and right above the objective lens group. The stage is mounted on the rack in such a manner that the stage can be moved horizontally with the shooting position adjustable. A lens of the camera is combined with the different objective lenses subjected to rotational switching to focus on different levels of a mixed microscopic examination liquid in a counting pool of the stage. In this way, by changing the optical length of the objective lenses, multi-level objects in the counting pool are photographed, without any need of adjusting the stage; low machining precision is required, and the method is easy to achieve with high control accuracy; the detection speed and shooting clarity are greatly improved; the photographing system is simple in structure, long in service life, stable in performance, convenient for operation, and good for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of multi-layer photographing for microscope inspection, and in particular relates to a multi-layer photograph method and a photographing system for microscope mirror inspection. Background technique [0002] At present, in microscopic analysis, since the mixed liquid for microscopic examination (such as the liquid after dilution and mixing of feces) contains more impurities and has different densities, it will sink and float at different levels. In order to photograph different levels, the existing microscopes usually use By adjusting the position of the stage up and down to realize the target objects in different layers in the shooting and counting pool. However, due to the structure of adjusting the stage up and down, due to the low machining accuracy, the assembly difference between the components, and the aging of the entire lifting system for up and down adjustment, the focus fails after frequent liftin...
