In this design, by setting a phase plate inside the 40X objective lens, the optical path difference of the visible light passing through the specimen is converted into an amplitude difference, thereby improving the contrast between various structures of the specimen, making various structures clearly visible when not stained or not obviously stained; by setting an annular aperture, the scattered light directed to the specimen can be suppressed, thereby improving the resolution and contrast of the specimen image. At the same time, the light passing through the annular aperture will form a conical light cone, and the focus of the light cone will be concentrated on the specimen, so that only the central light from the specimen can pass through the lens, enhancing the depth of the focal plane of the lens and making the image clearer.
