Biological microscope metering calibration device

Abstract

The invention discloses a biological microscope metering calibration device, and particularly relates to the field of microscope metering. The biological microscope metering calibration device comprises a main frame, one side of the main frame is provided with a lens cone, the top end of the lens cone is fixedly provided with an ocular lens frame, and the bottom end of one side of the main frame is fixedly provided with an objective table. According to the invention, by arranging a calibration ruler, a knob, a sliding block and side plates, when the height of the lens cone needs to be adjusted, the knob on the main frame can be rotated, a screw rod in an inner groove is driven to rotate through the knob, and the sliding block is driven to move up and down, so that the lens cone is driven to move up and down through a connecting block. During the adjusting process, the side plates at the two sides of the sliding block can move along the side grooves, so that the stability of the up-and-down movement of the lens cone is ensured, the left-and-right deviation is avoided, people can observe the positions of the side plates on the calibration ruler. When the side plates at the two sidesare on the same numerical value of the calibration ruler, the lens cone is in a vertical state and does not deviate, so that the lens cone can be calibrated more accurately.

Description

technical field [0001] The invention relates to the field of microscope metrology, more specifically, the invention relates to a biological microscope metrology calibration device. Background technique [0002] Biological microscopes are used for observation and research of biological slices, biological cells, bacteria, living tissue culture, fluid precipitation, etc. At the same time, they can observe other transparent or translucent objects as well as powders, fine particles and other objects. Adjust the lens and lens barrel. [0003] However, when the above-mentioned technical solution is used in practice, such as in the process of adjusting the existing lens and lens barrel, certain errors often occur, resulting in poor viewing angles for objects. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a biological microscope measurement and calibration device, by setting the...
