Problems solved by technology

However, no matter which method is used, the distance between the objective lens and the sample will change to a certain extent during the inclination adjustment process, which will cause the surface of the sample to be tested to be out of focus. At this time, it is necessary to refocus before continuing to observe, so the adjustment process is very cumbersome

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] In the description of the accompanying drawings of the present invention, the distribution mode of the threaded handwheel is an isosceles triangle, but it does not mean that the present invention must determine the position of the threaded handwheel in this distribution mode, and other modes of triangular distribution are also described in the present invention range, and therefore should not be construed as limiting the invention.

[0020] In the description of the accompanying drawings of the present invention, the threaded handwheel may have other structural forms, which does not mean that the present invention must design the threaded handwheel in this style, so it should not be construed as a limitation to the present invention.

[0021] Such as figure 1 — Figure 8 As shown, the stage level adjuster with height fine-tuning function provid...

Abstract

The utility model discloses an objective table levelness adjuster with a height fine adjustment function. The adjuster comprises a base, three threaded sleeves, three threaded hand wheels, a supporting table, a plurality of springs and a plurality of spring bayonet locks, the objective table levelness adjustor with the height fine adjustment function has the following beneficial effects that 1. three threaded hand wheels are adopted to achieve levelness adjustment of the objective table, meanwhile, the height of the supporting table can be finely adjusted, it can be guaranteed that the surfaceof a sample is not defocused in the adjusting process, and the problem that re-focusing is needed when the posture of the sample is adjusted is solved. 2, the function of adjusting the objective table in three degrees of freedom, namely pitching, deflection and lifting in the vertical direction, is realized; and meanwhile, the combined function of the two swing sliding tables and the lifting sliding table is achieved, and the integration degree of the objective table is improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for microscopes, and in particular relates to a stage levelness regulator with a height fine-tuning function. Background technique [0002] Due to errors in the manufacturing and installation process or a certain inclination on the surface of the sample, it is generally necessary to adjust the attitude of the sample to be tested when observing and measuring the sample with a microscope, so as to obtain better results under a suitable viewing angle. However, currently commonly used swing slides can only achieve angle adjustment in one degree of freedom, so two swing slides are needed to achieve adjustment in two degrees of freedom in pitch and yaw. The adjustment frame of some equipment uses a steel ball and two threaded handwheels as the fulcrum to realize the angle adjustment in the two degrees of freedom of pitch and yaw. However, no matter which method is used above, the distance b...
