The structural principle, characteristics, and application scope of stereomicroscope
Stereoscopic microscope, also known as solid microscope or operational and anatomical microscope. It is a visual instrument with a positive stereoscopic effect. The optical structure principle is composed of a shared primary objective, which separates the two beams of light after imaging the object by two sets of intermediate objective lenses, also known as zoom lenses, and forms a certain angle called volumetric angle. Generally, the viewing angle is 12-15 degrees, and then 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 characteristics of stereomicroscope:
A large field of view diameter and depth of focus make it easy to observe all aspects of the detected object; Although the magnification is not as good as conventional microscopes, their working distance is very long; It appears to be upright and easy to operate, due to the prism below the eyepiece reversing the image. According to actual usage requirements, current stereo microscopes can be equipped with a variety of accessories. For example, if you want to obtain a larger magnification, you can choose eyepieces and auxiliary lenses with higher magnification. A digital imaging system can be formed through various digital interfaces and digital cameras, cameras, electronic eyepieces, and image analysis software to connect to the computer for analysis and processing. The lighting system also has reflected and transmitted light illumination, and light sources include halogen lamps, ring lamps, fluorescent lamps, cold light sources, and so on.
The application range of stereomicroscope:
Based on the optical principles and characteristics of stereomicroscopes, their widespread application in industrial production and scientific research is determined. For example, in the fields of biology and medicine, it is used for slicing operations and microsurgery; Used in industry for observation, assembly, inspection, and other work of small parts and integrated circuits.
