The difference between stereomicroscope and biological microscope
The imaging results are different from the machine structure: a stereoscopic microscope has a dual optical path, forming an angle, imitating human eye imaging, and seeing objects with a sense of stereoscopy; A typical biological microscope has a single optical path and is simply divided into two eyepieces for easy viewing in the human eye.
Stereoscopic microscopes have small magnification, ranging from tens to 300 times, and have a large working distance, allowing for viewing large samples, dissecting, and more; The biological microscope has a small magnification, up to 1000 times, and a small working distance, so it only needs to look at some slices and so on.
Stereoscopic microscope, also known as a "solid microscope" or "dissecting microscope", is a visual instrument with a stereoscopic effect and is widely used in various departments of biology, medicine, agriculture, forestry, industry, and marine biology.
A biological microscope is used to observe and study biological sections, biological cells, bacteria, and live tissue culture, fluid precipitation, etc. It can also observe other transparent or semi transparent objects, as well as powders, small particles, and other objects. The left image shows the inverted biological microscope type produced, which is also a necessary inspection equipment for QS and HACCP certification in food and drinking water plants.
The difference between stereomicroscopes and biological microscopes can be distinguished from the following points:
1. Imaging effect: The reason why a stereoscopic microscope is called stereoscopic is because it can observe three-dimensional samples and form a three-dimensional image; Biological microscopes can only observe flat samples. The reason is that the depth of field of a stereoscopic microscope is much larger than that of a biological microscope.
2. Magnification and resolution: The most conventional objective magnification of a stereoscopic microscope is 0.65X~4.5X, while the better ones are 0.75X~7.5X,
The imported products can reach more than ten times, and the volume can continuously increase; The objective of a biological microscope is generally fixed at a magnification of 4X 10X 40X 100X. The resolution of biological microscopes is much higher at the same magnification, except for special ones
3. Application field: Stereoscopic microscopes are widely used in biology, medicine, agriculture, etc; Electronic circuits, microelectronics, chips, etc;
Metal accessories, heat treatment, etc. Biology is generally only used in fields such as biology, medicine, agriculture, etc. Because stereopsis can observe transparent and semi transparent samples, organisms can only observe transparent samples.
