The Difference Between Stereo Microscope and Biological Microscope
The imaging results are different from the machine structure: the stereo microscope has dual light paths, forming an angle, imitating human eye imaging, and the objects seen have a sense of three dimensionality; A typical biological microscope has a single optical path and is divided into two eyepieces for the convenience of viewing in the human eye.
Stereoscopic microscopes have small magnification, ranging from tens of times to up to 300 times. They have a long working distance and can observe large samples, dissections, etc; The biological microscope has a small magnification, up to 1000 times, and a small working distance, so it only looks at slices and other materials.
Stereoscopic microscope, also known as "solid microscope" or "dissecting microscope", is a visual instrument with a stereoscopic effect, widely used in various fields such as biology, medicine, agriculture, forestry, industry, and marine biology.
Biological microscope is used for observing and studying biological slices, biological cells, bacteria, 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 figure shows the inverted biological microscope used in production, which is also an essential inspection equipment for QS and HACCP certification in food and drinking water plants.
The difference between a stereomicroscope and a biological microscope can be distinguished from the following points:
1. Imaging effect: The reason why stereomicroscopes are called stereomicroscopes is because they can observe three-dimensional samples and create three-dimensional images; Biological microscopes 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 magnification for stereomicroscopes is 0.65X~4.5X, while the better ones are 0.75X~7.5X. Imported products can achieve up to ten times magnification, and stereomicroscopes can continuously change magnification; The objective lens of a biological microscope is generally fixed at a magnification of 4X, 10X, 40X, or 100X. The resolution of a biological microscope is much higher at the same magnification, except for special cases
3. Application areas: Stereoscopic microscopes are widely used in biology, medicine, agriculture, and other fields; Electronic circuits, microelectronics, chips, etc; Metal accessories, heat treatment, etc. Biology is generally only used in fields such as biology, medicine, agriculture, etc. Because stereoscopy can observe transparent and semi transparent samples, organisms can only observe transparent samples.
