Object lens driving table

Abstract

The invention belongs to the field of micro driving application and relates to an object lens driving table and specifically to an object lens driving table using a hinge mechanism to magnify output displacement. The object lens driving table is used for fixing an object lens ring and comprises a hollow housing and an actuating member disposed on the housing. The hollow housing comprises a housing portion and a chamber passing through the housing portion. The hinge mechanism is arranged on the housing portion and comprises a moving portion and a moving platform connected with the moving portion. The actuating member is abutted against the moving portion. The object lens ring is arranged in the chamber and is fixed to the moving platform. According to the object lens driving table, the hollow housing is provided; the hinge mechanism is disposed on the housing; the object lens ring is disposed on the moving platform of the hinge mechanism; and the actuating member is abutted against the moving portion of the hinge mechanism. Thus, the hinge mechanism magnifies the motion transmitted by the micro displacement of the actuating member in a gapless and uncoupled manner so as to effectively increase a motion magnification factor and guarantee size compactness.

Description

technical field [0001] The invention belongs to the field of micro-drive applications, and relates to an objective lens driving platform, in particular to an objective lens driving platform for amplifying the output displacement by using a hinge mechanism. Background technique [0002] At present, in biology, the optical microscope has always been a powerful tool for people to explore the microcosm, and people have continuously deepened their cognition of the microcosm by using it. The development of optical microscopes plays a key role in human understanding of life phenomena. With the continuous advancement of the level of science and technology, the application field of optical microscopes is expanding, and at the same time, its imaging quality is constantly improving. With the needs of social development, people's demand for the observation of the three-dimensional structure inside the microscopic sample is increasing, which puts forward extremely high requirements for ...

AI Technical Summary

Problems solved by technology

However, the clarity of traditional optical microscopes depends entirely on the magnification of the optical objective lens, and the maximum magnification of the current optical objective lens can only reach 1600 times (the resolution of the human eye is about 1mm, taking 1600 times magnification as an example, the minimum Observation accuracy 0.625 microns)

Obviously the traditional optical microscope can no longer meet the demand here

[0003] However, at present, the existing objective lens driving devices are generally driven by motors or manually adjusted. Such devices have disadvantages such as insufficient precision, slow response time, large volume and high noise.
