Problems solved by technology

[0004] However, this technology has certain limitations. This technology is limited by the size of the microscope system. The number of magnet groups installed on the working position switching device is always limited. When the number of working positions to be identified exceeds this limited number number, the existing location recognition devices cannot meet the requirements
In addition, the existing position recognition device has relatively strict requirements on the distance between the magnet group and the Hall sensor. If the distance exceeds this requirement, the Hall sensor will not sense the signal.
This also brings more constraints to the design of the microscope system

Abstract

The invention relates to the field of microscopes and discloses a microscope continuous position identification device. The device comprises a machine frame, a working position switching mechanism, a potentiometer and a control circuit, wherein the working position switching mechanism is connected with the machine frame in a pivoting mode and can make continuous linear motion or continuous rotational motion along a certain axis on the machine frame; the potentiometer comprises a center tap, the center tap is fixed on the working position switching mechanism and can move synchronous with the working positioning switching mechanism, and each instant working position of the working position switching mechanism corresponds to a unique potentiometer resistance variable quantity; the control circuit is connected with the potentiometer, a memory is arranged in the control circuit, and the information of the correspondence between the potentiometer resistance variable quantities and the working positions of the working position switching mechanism is stored in the memory. According to the device, a large number of working positions can be identified, dimensional limitation is avoided, and the potentiometer is highly sensitive to signals without being affected by distance.

Description

technical field [0001] The invention relates to the field of microscopes, in particular to a continuous position recognition device for a microscope. Background technique [0002] In microscopic observation, according to observation needs, sometimes a microscope with continuous zoom is used. For the marking of the magnification of the continuous zoom microscope, the usual practice is to print the magnification mark on the zoom handwheel. Due to the limited area of ​​the zoom handwheel, the magnification that can be marked is also limited. If the observer turns the zoom handwheel to the middle position between the two magnification marks, the magnification of the microscope cannot be accurately known at this time. In order to better meet the needs of the observer, it is necessary to know and mark the current magnification of the continuous zoom microscope when the zoom handwheel is turned to any position. To this end, we need to continuously identify any working position o...
