3-DOF (degree of freedom) mobile loading platform for vertical optical microscope

Abstract

The invention discloses a 3-DOF (degree of freedom) mobile loading platform for a vertical optical microscope. An optical source is disposed on a horizontal position adjustment platform. One end of a lifting rod is fixed with the horizontal position adjustment platform, and the other end extends into a bottom seat. A displacement adjustment handle driving the lifting rod to move upward along a vertical direction in the bottom seat is disposed on the bottom seat. The horizontal position adjustment platform comprises two horizontal displacement guide blocks, two horizontal displacement adjustment handles, and a base seat. The two horizontal displacement guide blocks are disposed along the vertical direction on the bottom seat. The sides of the horizontal position adjustment platform are respectively provided with the horizontal displacement adjustment handle driving the horizontal displacement guide block at an upper layer to move along a horizontal direction on the horizontal displacement guide block at a lower layer, and the horizontal displacement adjustment handle driving the horizontal displacement guide block at the lower layer to move along the horizontal direction on the bottom seat. The moving directions of the two horizontal displacement guide blocks are perpendicular to each other. According to the invention, an observed object can be quantitatively moved in the horizontal direction, and the focusing accuracy of a lens barrel can also be improved.

Description

technical field [0001] The invention belongs to the technical field of optical measurement auxiliary equipment, in particular to a three-degree-of-freedom mobile loading platform for a vertical optical microscope. Background technique [0002] Optical microscopes can provide direct, clear and rich information on the microscopic surface or phenomena of materials, which is convenient for people to conduct in-depth research and exploration on them. The vertical optical microscope is one of the main forms, and the observation object is placed directly under the eyepiece and objective lens. In a general-purpose upright optical microscope, only the lens barrel can move up and down, which is convenient for adjusting the focus. At high magnifications, the area shown in the lens is a very small part of the object being observed, requiring precise horizontal movement of the object to observe adjacent areas; on the other hand, at high magnifications, a particularly strong Only when t...

AI Technical Summary

Problems solved by technology

But it can only solve the problem of poor imaging effect caused by the unevenness of the stage or sample under high magnification

It cannot move the observed object accurately and quantitatively in the horizontal direction, which is exactly what must be done in order to obtain a larger area image at high magnification

This technical problem has not been solved in the upright optical microscope at present
