Principle and structure of the stereomicroscope
Principles and Structure of Stereoscopic Microscopes: Stereoscopic microscopes can also be referred to as solid microscopes, stereomicroscopes, and anatomical microscopes. It is a visual instrument with a stereoscopic effect of positive images. The principle and structure of a stereoscopic microscope are based on a shared primary objective lens. The two beams of light after imaging an object are separated by two sets of intermediate objectives, also known as zoom lenses. It is a visual instrument with a stereoscopic effect of positive images. The principle and structure of a stereo microscope are based on a shared primary objective lens. The two beams of light that image an object are separated by two sets of intermediate objectives, also known as zoom lenses, and form a certain angle called the body viewing angle. Generally, it is 12 degrees to 15 degrees, and then imaged through their respective eyepieces. The magnification change is obtained by changing the distance between the intermediate lens groups. 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 stereoscopic image for both eyes. It is essentially two single tube microscopes placed side by side, with the optical axes of the two tubes forming a perspective equivalent to that formed when observing an object with both eyes, thus creating a three-dimensional stereoscopic image.
Its characteristics are: large field of view diameter and depth of focus, which facilitate the observation of all aspects of the detected object; Although the magnification is not as good as conventional microscopes, their working distance is long; It looks upright, making it easy to operate, because the prism under the eyepiece reverses the image. According to actual usage requirements, current stereomicroscopes can be equipped with a variety of accessories. For example, if you want to obtain a larger magnification, you can choose a higher magnification eyepiece and microscope auxiliary objective lens. A digital imaging system can be formed through various digital interfaces and digital cameras, microscope cameras, electronic eyepieces, and image analysis software to connect to a computer for analysis and processing. The lighting system also includes reflected light and transmitted light illumination, and the light sources include halogen lamps, ring LED lamps, fluorescent lamps, cold light sources, etc. The principle and characteristics of stereomicroscope determine its wide application in industrial production and scientific research.
