The difference between stereoscopic microscope and ordinary optical microscope
An ordinary optical microscope is a precise optical instrument. In the past, simple microscopes were only composed of a few lenses, while currently used microscopes consist of a set of lenses. Ordinary optical microscopes can usually magnify objects by 1500-2000 times. The structure of an ordinary optical microscope can be divided into two parts: a mechanical device and an optical system. These two parts are well coordinated to play the role of a microscope.
Stereomicroscope
The principle and structure of a stereoscopic microscope are composed of a common primary objective lens. After imaging an object, the two beams of light are separated by two sets of intermediate objective lenses, also known as zoom lenses, and form a certain angle called the volumetric angle. Generally, the viewing angle is 12 degrees to 15 degrees. After imaging through each eyepiece, the magnification change is obtained by changing the distance between the intermediate lens groups. By using a dual channel optical path, the left and right beams in the binocular lens tube are not parallel, It has a certain angle, providing a three-dimensional image for the left and right eyes. It essentially consists of two single tube microscopes placed side by side, with the optical axes of the two tubes forming the perspective formed when people observe an object with their binoculars, thereby forming a three-dimensional visual image.
The difference between the two:
The usage method of stereoscopic microscope is similar to that of ordinary optical microscope, but it is more convenient. The main difference between the two is that the microscopic examination object of stereoscopic microscope pot does not need to be made into a piece; The stereoscopic microscope cutting table is directly fixed on the mirror base and equipped with a black and white double-sided plate or glass plate. The operator can choose according to the object and requirements of the mirror inspection; The imaging of a stereoscopic microscope is upright, making it easy to distinguish orientation during anatomical operations. The objective lens of a stereoscopic microscope is only one, and its magnification can be continuously adjusted by rotating the spiral.
