[0002] In the microscopic imaging process, the illumination mode of light source is an important factor affecting the observation effect, and an unsuitable light source can cause the microscopic image to appear uneven brightness, insufficient brightness, limited illumination angle and other problems. There are two kinds of mainstream illumination modes on the current microscope market: one is ring illumination, and the other is single-side illumination. The advantage of ring illumination is uniform illumination and can provide 360° full-angle illumination, but the light blocking problem is easily caused by the structure of the microscope stage and other structures, and the tilt angle of ring illumination is single, which cannot meet the specific needs. The single-side illumination is concentrated, the image brightness is high, and the tilt angle of the illumination can be adjusted, but it can only illuminate at a fixed circumferential position, which may not cover the entire sample, resulting in insufficient illumination in some areas and inability to observe the sample comprehensively.
