The structural principle, characteristics and application range of stereo microscope
A stereo microscope, also known as a dissecting microscope or a low-power microscope, is an optical instrument designed to provide a three-dimensional view of the object being observed. Unlike conventional compound microscopes, it uses a dual optical path system that mimics human binocular vision, offering a more natural and intuitive visual experience. The basic structure of a stereo microscope consists of two separate optical paths: one for the left eye and one for the right. Each path includes its own objective lens, intermediate lenses (also called zoom mirrors), and an eyepiece. These components work together to create a stereoscopic image by maintaining a small angle between the two optical axes—typically around 12 to 15 degrees. This angle simulates the natural viewing angle of human eyes, allowing the observer to perceive depth and spatial relationships effectively. One of the key advantages of a stereo microscope is its large field of view and deep depth of focus. This makes it ideal for examining objects with complex surface structures, such as biological specimens, mechanical parts, and electronic components. While its magnification range is generally lower than that of a compound microscope, it offers a much longer working distance, which is essential for handling delicate or bulky samples during procedures like dissection, assembly, or inspection. The image produced by a stereo microscope is upright, making it easier to manipulate objects under the microscope. This feature is achieved through the use of prisms in the eyepieces, which correct the orientation of the image. Additionally, modern stereo microscopes are highly customizable, with a wide range of accessories available. These include high-magnification eyepieces, auxiliary objectives, digital cameras, and electronic eyepieces that allow for real-time imaging and analysis on computers. Lighting systems in stereo microscopes can vary, including both reflected and transmitted illumination options. Common light sources include halogen lamps, ring lights, fluorescent lamps, and cold light sources, each suited for different types of samples and applications. The flexibility of the lighting system enhances the visibility and clarity of the specimen under observation. Due to its versatility and user-friendly design, the stereo microscope is widely used in various fields. In biology and medicine, it is commonly employed for tasks such as tissue slicing, microsurgery, and histological examination. In industrial settings, it plays a crucial role in quality control, component inspection, and the assembly of small or intricate parts, such as those found in electronics and precision engineering.
