The difference between ultrasonic scanning microscope and ordinary optical microscope

In order to solve the practical problems in production and life, the ultrasonic scanning microscope came into being. It can provide professional solutions for many imaging. There is a great difference between the ultrasonic scanning microscope and the ordinary optical microscope. In terms of working principle, it has The high-frequency ultrasonic transducer with focusing function, the working mode of the ultrasonic scanning microscope is also called point-by-point scanning in the industry. It is the inspection of the inside of the material. Its imaging image is the image of the internal structure, and the nano-level resolution is better than the peripheral products. , The following editor will introduce the difference between the ultrasonic scanning microscope and the ordinary optical microscope in detail.

The difference between ultrasonic scanning microscope and ordinary optical microscope

1. First, the ultrasonic scanning microscope is not completely different from the optical scanning microscope. The similarity between them is "displaying the microscopic image of the tested sample", while the latter is the microscopic image of the surface, and the former is the internal microscopic image; in some In special industries and special fields, it is precisely the internal imaging of the ultrasonic scanning microscope. From the principle of action, the optical mirror is visible light, and the ultrasonic scanning microscope is naturally ultrasonic.

2. In addition, from the perspective of pixels, the two of them also have this fundamental difference. Ultrasonic microscopes are reflected by pixel pixels, but the optical lens is mainly CCD camera. It is also because of the difference in structure, so the ultrasonic scanning microscope The price is several times that of ordinary industrial microscopes. Not only that, but there is also a huge gap in their application fields. Ultrasonic scanning microscopes cover almost all fields of optical microscopes, and they are especially widely used in the material semiconductor industry.

3. The technological content is different. It is difficult to understand the difference in the types of scanning microscopes as a "layman", but the professional ultrasonic scanning microscope R&D personnel said that the two types of microscopes should not be distinguished conceptually, but ultrasonic scanning can be said in a nutshell. The scientific and technological content of the microscope is higher, and it has a higher level of requirements for production.

Although there are many differences between ultrasonic scanning microscopes and ordinary optical microscopes, they also perform their own duties. There is no distinction between advantages and disadvantages. In different fields, you only need to choose according to the use situation. Because ultrasonic scanning microscopes are more offline Rare, so many companies have limitations on the understanding of this kind of microscope, so it is necessary to increase the detailed understanding of the ultrasound scanning microscope.
