On several popular common microscope types
There are different types of microscopes, each serving a different purpose. Some are suitable for biological applications, while others are used in educational institutions. There are also microscope types available for metallurgy and studying 3D samples. In this article, we will learn about microscopy together.
First, let's understand what a microscope is. A microscope is an optical instrument composed of a lens or a combination of several lenses, and it is a sign that human beings have entered the atomic age. Microscopes can be divided into the following four categories according to the microscopic principle:
- Polarizing microscope,
- Optical microscope,
- electron microscope,
- digital microscope, etc.
Now let's take a look at polarized light microscopy: Polarizing microscopes are microscopes used to study so-called transparent and opaque anisotropic materials, and have important applications in science and engineering majors such as geology. All substances with birefringence can be clearly distinguished under a polarizing microscope.
Of course, these substances can also be observed by staining, but some are not available and polarizing microscopes must be used. Reflective polarizing microscope is an essential instrument to study and identify birefringent substances by using the polarized light characteristics of light.
Optical microscopes usually consist of an optical part, an illumination part and a mechanical part. Undoubtedly the optical part is the most critical, it consists of eyepieces and objective lenses.Suitable for children, students, adults and beginners to carry out biological observation of mobile phone motherboard electronic parts welding in laboratory, school, mobile phone repair shop, home or field.
The electron microscope has the basic structural features similar to the optical microscope, but it has a much higher magnification and resolution ability than the optical microscope. It uses the electron flow as a new light source to image the object. 4 MP image sensor, industrial lens and adjustable stand, not only make the picture very clear, but also make it have 3D visual effect.
