Method for adjusting illumination light path of microscope

The invention discloses an adjustment method for a microscope illumination light path, and according to the adjustment method, fine adjustment of the illumination light path is completed step by step in a partitioned manner by setting a reasonable illumination light path structure and accurately adjusting and confirming the position of a window. Firstly, light rays of a light source are collimated and adjusted to form parallel light beams; a field diaphragm and an aperture diaphragm are arranged on a light path, and a light source image is presented at the aperture diaphragm; after the positions of the tube lens and the turntable are determined, the light path assembly from the light source to the tube lens is completed by observing a field diaphragm image on the turntable; and finally, arranging an observation window on one side of the tube lens close to the position where the microscope objective is mounted, and adjusting an observation light source image to determine the position of the objective.
