Video measuring instrument manufacturers talk about the difference between optical magnification and image magnification
At present, image measuring instruments play an important role in the field of industrial inspection and measurement technology. In order to be able to develop better, let us briefly introduce the working principle of the image measuring instrument, so that friends who do not know the image measuring instrument can get acquainted briefly.
This image measuring instrument is the result of continuous improvement and development of current digital technology. This process also works closely with computers and other hardware. At the same time, special control and image software on the computer can be enough to turn the computer into light energy. The displacement value of the optical ruler can be read with the help of the relevant firmware, and the required result can be achieved with the help of the software module. At the same time, the personnel performing the measurement and operation can compare the images and find the gap. CCD digital imaging technology is the foundation of the invention of image measuring instruments.
At present, people have many questions about the optical amplifiers of image measuring instruments. What is the difference between large magnification and image magnification? Optical magnification is usually a fixed value, usually 0.35 times to 2.25 times or 0.75 times-4.5 times the value between these two intervals, we can use this number to multiply our objective lens value to get the magnification. We mentioned CCD digital imaging technology above. Optical magnification refers to the magnification of the object through the eyepiece to the CCD. On the other hand, image magnification usually refers to the actual object and image magnification. In fact, the difference between the two lies in the magnification method, not the magnified image size. The latter may use the processor in the CCD, which is not very clear. Choosing to use an optical lens structure to achieve magnification can ensure that the image effect is True, but Judging from the current development situation, both currently play important roles in different fields.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
