The difference between a stereo microscope and a biological microscope
The imaging results are different from the machine structure: a stereo microscope has a dual light path, forming an angle, imitating the human eye's imaging, and the objects seen have a three-dimensional effect; the general biological microscope has a single light path, which is divided into two for the convenience of the human eye. eyepiece.
Stereoscopic microscopes have small magnifications, ranging from dozens of times to about three hundred times, and have a large working distance, so they can view large samples, dissections, etc.; biological microscopes have small magnifications, up to 1,000 times, and have a small working distance, so they can only view slices, etc.
Stereo microscope, also known as "solid microscope" or "anatomy microscope", is a visual instrument with an upright three-dimensional sense. It is widely used in various departments of biology, medicine, agriculture, forestry, industry and marine biology.
Biological microscopes are used to observe and study biological slices, biological cells, bacteria, living tissue culture, fluid sedimentation, etc. It can also observe other transparent or translucent objects as well as powders, fine particles and other objects. The picture on the left shows the inverted biological microscope produced. This biological microscope is also a necessary inspection equipment for food factories and drinking water plants to obtain QS and HACCP certification.
The difference between a stereomicroscope and a biological microscope can be distinguished from the following points:
1. Imaging effect: The reason why a stereo microscope is called a stereo microscope is because it can observe three-dimensional samples and form a three-dimensional image; while biological microscopy
The mirror can only observe flat samples. The reason is that the depth of field of a stereomicroscope is much larger than that of a biological microscope.
2. Magnification and resolution: The most common objective lens magnification of a stereo microscope is 0.65X~4.5X, and the better ones are 0.75X~7.5X.
Imported products can be magnified to more than ten times, and stereoscopic vision can be continuously zoomed; biological microscope objectives are generally
4X\10X\40X\100X multiples are fixed. The resolution of a biological microscope is much higher at the same magnification, except for special cases
3. Application fields: Stereo microscopes are widely used in biology, medicine, agriculture, etc.; electronic circuits, microelectronics, chips, etc.;
Metal fittings, heat treatment, etc. Biology is generally only used in biology, medicine, agriculture, etc. Because stereo vision can
Observe transparent and translucent samples, organisms can only observe transparent samples
