Digital microscope structure with horizontal optical path for fully-automatic scanning

Abstract

The invention provides a digital microscope structure with a horizontal optical path for fully-automatic scanning. The digital microscope structure comprises an illumination module, a scanning feed module, an objective lens module, a linear driving focusing module, an infinity imaging optical path module and a camera. The optical axes of the illumination module, the objective lens and the infinity imaging optical path module are parallel to a horizontal plane. A slice to be tested is mounted on the scanning feed module. The light emitted by the illumination module successively passes through the slice to be tested, and the objective lens module and the infinity imaging optical path module to enter the camera. The objective lens module is mounted on the linear driving focusing module, and the linear driving focusing module drives the objective lens module to reciprocate in the optical axis direction. The digital microscope structure uses the horizontal optical path parallel to the horizontal plane. The focusing motion does not need to overcome the gravity of an objective lens switching system or a traditional objective table system. The digital microscope structure improves the focusing performance in a full-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.

Problems solved by technology

[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 driving method has inherent defects such as backlash and vibration that are difficult to overcome. At the same time, the dynamic characteristics are poor, and it is difficult to meet the frequent focus movement requirements of the high-speed scanning process.
