[0002] The comparative microscope belongs to a special microscope, which not only has the function of an ordinary microscope, but also can observe the specimen images under the left and right microscopes simultaneously through an ocular lens. By means of docking, cutting, overlapping, rotating and the like, two or more objects can be compared macroscopically or microscopically to check the tiny differences in form, organization, structure, color or material, so as to achieve the purpose of identification and comparison. The comparative microscope is suitable for the basic work of evidence identification in a criminal science laboratory, and is also suitable for the fields of police colleges, banks, tax authorities, printing, coinage, archaeology, biological engineering and agricultural science, but the existing comparative microscope system principle as shown in Figure 2 the left light path passes through an objective lens, a turning prism, and is divided into a left first light path and a left second light path at a combining prism, wherein the left first light path will continue to pass through a second lens into a light splitting prism and be divided into two light paths again, and after light splitting, enter an ocular lens through a mirror, and the left second light path will no longer participate in imaging after light splitting at the combining prism; the right light path passes through an objective lens, a turning prism, and a compensating mirror, and is divided into a right first light path and a right second light path at a combining prism, wherein the right first light path will continue to pass through a second lens into a light splitting prism and be divided into two light paths again, and after light splitting, enter an ocular lens through a mirror, and the right second light path will no longer participate in imaging after light splitting at the combining prism, so that the left second light path and the right second light path no longer participate in imaging, resulting in a loss of half of the light energy of the entire comparative microscope system; when the left and right objective lenses image the objects directly below the turning prism and the combining prism at the field stop, the human eye can observe the enlarged images of the left and right objects simultaneously through the same set of ocular lenses; when the combining prism is used for combining images, half of the light energy is always lost, although this can be compensated by increasing the power of the light source and the like, but this requires double the amount, and at the same time, the heat dissipation function needs to be improved to ensure the service life of the lighting device, and the cost is relatively increased.
