Binocular stereoscopic microscope provides stereoscopic images for left and right eyes by using dual-channel optical path. In essence, two single-barrel microscopes are placed side by side, and the optical axes of the two barrels form the perspective formed when people observe an object with their eyes, thus forming a stereoscopic vision image in three-dimensional space. Binocular stereomicroscope is widely used in biology and medicine, for slicing and microsurgery. It is used for the observation, assembly and inspection of micro parts and integrated circuits in industry.
In addition to the two eyes for observation, the three-eye microscope is also used to connect computers or digital cameras, which constitutes a computer-based xx (Biological/Metallographic ...) microscope and a digital xx microscope.
