[0002] An inverted microscope and a magnifying glass play the same role, which is to magnify a tiny object nearby for human observation, but a microscope can have a higher magnification than a magnifying glass. The function of the eyepiece is the same as that of a magnifying glass, the only difference is that what the eye sees through the eyepiece is not the object itself, but the image of the object that has been magnified once by the objective lens. The computer-type binocular inverted metallographic microscope is a product that has been successfully developed by combining optical microscope technology, photoelectric conversion technology, and computer image processing technology. It can be conveniently observed on a computer monitor. The metallographic image can be analyzed and graded on the metallographic map, and the pictures can be output and printed. The microscope has clear imaging, a wide field of view, and the overall design conforms to human-machine functions, suitable for long-term operation. It can be widely used in factories or laboratories for the identification of casting quality, the inspection of raw materials, or the research and analysis of the metallographic structure after material processing.
