Among them, the regulator is the size of the two helix on the lens post, which can be divided into the coarse quasi focus screw and the fine quasi focus screw, which can adjust the moving of the mirror table. The name of each part of the microscope eyepiece and objective lens are the main structure of the microscope and the structure for observing and amplifying the object image.
