Some little knowledge about the microscope
1. When using a microscope, what is the relationship between resolution and magnification?
Resolution is the ability to clearly distinguish between two adjacent points and separate them, that is, the smallest diameter of a visible object. It is useless to increase the magnification without increasing the resolution, that is, it is useless to increase the microscope several times when the resolution is not good, because the resulting image may be unclear or blurred.
2. How is the clarity of the microscope affected?
"Resolution" and "contrast" will affect the clarity of the image. The resolution of the microscope is the minimum distance between two points that can be distinguished under the microscope. If the resolution value of a microscope is 0.3 μm, it means that if the distance between two points is greater than 0.3 μm, Then two points can be distinguished under the microscope, and if it is less than 0.3 μm, it will be regarded as one point. As an example:
The human naked eye has a resolution of 200um (=0.2mm) at a distance of 25cm, which means that if the distance between these two points is less than 200um, we cannot see clearly.
3. How to clean the microscope lens if it is blurred with gum?
Method 1: Wipe the microscope lens with a cotton ball dipped in absolute ethanol
Method 2: Use lens cleaning paper dipped in xylene to wipe the lens, which is easy to remove.
4. Where can a stereo microscope be used?
1. In the electronics industry, the most common one is of course circuit boards;
2. In the paper industry, identify the authenticity of documents and banknotes;
3. In the textile industry, the inspection of cotton wool tissue is not up to standard;
4. Detection of small parts, etc.
5. What is the electronic eyepiece of metallographic microscope?
The electronic eyepiece of the metallographic microscope has a resolution of 1.3-3 million pixels, which is suitable for shooting with any standard biological microscope, stereo microscope, and metallographic microscope. It can be widely used in medical and health institutions, laboratories, research institutes, and colleges and universities. Biology, pathology, bacteriological observation, teaching and research, clinical experiments and routine medical inspections, analysis and identification of materials in factories and laboratories.
