Difference between stereomicroscope and optical microscope
A regular optical microscope is a precise optical instrument. In the past, a simple microscope was only composed of a few lenses, while the current microscope is composed of a set of lenses. Ordinary optical microscopes can usually magnify objects by 1500-2000 times. The structure of a regular optical microscope can be divided into two parts: a mechanical device and an optical system. Only when these two parts are well coordinated can the microscope function effectively.
Stereo microscope
The principle and structure of a stereo microscope are composed of a shared primary objective, which separates the two beams of light after imaging the object from two sets of intermediate objective lenses, also known as zoom lenses, and forms a certain angle called the volumetric angle. Generally, it is 12 to 15 degrees, and then imaged through their respective eyepieces. 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 tube are not parallel, but have a certain angle, providing a three-dimensional image for the left and right eyes. It is essentially two single tube microscopes placed side by side, with the optical axes of the two tubes forming the perspective formed by people observing an object with their binoculars, thus forming a three-dimensional visual image.
The difference between the two:
The usage method of stereo microscope is similar to that of ordinary optical microscope, but it is more convenient. The main difference between the two is that the object of stereo microscope examination does not need to be made into a mounting piece; The stereo microscope cutting table is directly fixed on the mirror base and equipped with black and white double-sided plates or glass plates. The operator can choose according to the object and requirements of the mirror inspection; The imaging of a stereo microscope is upright, making it easy to distinguish orientation during anatomical operations. The objective lens of a stereo microscope is only one, and its magnification can be continuously adjusted by rotating and adjusting the spiral.
