Abstract

The invention provides a digital microscope structure with an optical path horizontally used for fully automatic scanning, including: an illumination module, a scanning feed module, an objective lens module, a linear drive focusing module, an infinity imaging optical path module, and a camera; the illumination module, The optical axes of the objective lens and the infinity imaging optical path module are parallel to the horizontal plane; the slice to be measured is installed on the scanning feed module, and the light emitted by the illumination module passes through the slice to be measured and the objective lens module in sequence And the infinity imaging optical path module enters the camera; the objective lens module is installed on the linear drive focus module, and the linear drive focus module drives the objective lens module to move back and forth in the direction of the optical axis. Adopting a horizontal optical path parallel to the horizontal plane, the focusing movement does not need to overcome the gravity of the objective lens switching system or the traditional stage system, which improves the focusing performance in the fully automatic scanning process.

Description

technical field [0001] The invention relates to the technical field of microscopes and electromechanical design, in particular to a digital microscope structure with horizontal optical paths for fully automatic scanning. Background technique [0002] At present, fully automatic scanning digital microscopes all adopt the form of vertical optical path, such as classic upright microscope and inverted microscope structure, which are characterized in that the optical axis of the objective lens is perpendicular to the horizontal plane, and the diagonal movement is also perpendicular to the horizontal plane. The autofocus system must overcome The gravity of the stage system or objective lens switching system is required to achieve autofocus. [0003] The focus system of this type of microscope mostly adopts a driving method with a large thrust such as rack and pinion and screw nut transmission, which has the ability to overcome gravity and self-lock. The transmission system of this...
