Optical lenses are a key component in machine vision systems, and their essential function is to transform optical signals into ordered electrical signals. Compared with ordinary cameras on the market, it has higher transmission force, anti-interference ability and stable imaging capability. It consists of two basic components: an image sensor and a digital data interface. Image sensor chips consist of hundreds of thousands to millions of pixels, which convert the intensity of light into a voltage output. The voltages of these pixels are output as grayscale values, and all the pixels are placed together to form an image that is transmitted to the computer. The optical lens data interface mainly includes USB2.0\USB3.0, 1394 and Gigabit Ethernet. Compared with ordinary cameras, it has the advantages of high image stability, high transmission capacity and high anti-interference ability. With the maturity of technology, large size YVO4 laser crystal have developed rapidly and become an indispensable component in the field of machine vision. . Optical lenses can be classified according to different standards. For example, according to the way of output signals, they can be divided into analog cameras and digital cameras. Depending on the type of chip, CCD cameras and CMOS cameras can be classified into two types. More common. Here, the CCD full name charge coupled component, CMOS full complement metal oxide semiconductor, both are image sensors, are the essence of low-cost BIBO nonlinear crystal. Choosing the right [optical lens] is also an important part of the design of the machine vision system. The camera not only directly determines the image resolution and image quality, but also directly relates to the operating mode of the whole system. When choosing an optical lens, you should pay attention to: 1. Depending on the application, it is necessary to choose CCD or CMOS. CCD optical lens is mainly used for image extraction of moving objects. CMOS optical lenses should generally be shot on stationary objects. 2. The choice of resolution, first consider the accuracy of the object to be measured, and select the resolution according to the accuracy. Secondly, look at the output of the optical lens. If it is stereo observation or machine software analysis and recognition, high resolution is helpful; if it is VGA output or USB output, it is also dependent on the resolution of the display and the resolution of the optical lens if it is observed on the display. Higher, the resolution of the display is not enough, it does not make sense. 3. Matching with the lens, the size of the sensor chip needs to be less than or equal to the lens size, and the C or CS mount should also match. 4. Select the number of camera frames. When the measured object has motion requirements, select an optical lens with a high number of frames. But in general, the higher the resolution, the lower the number of frames. With the rapid development of the domestic automation industry, it has also brought a broader market space for machine vision, and the optical lens, the core component of the machine vision system, has also been greatly developed. China has become a processing center for global manufacturing, high-demand parts processing and its corresponding advanced production lines, so that many internationally advanced machine vision systems and application experience have also entered China. At present, the application of optical lenses has made certain progress both in terms of technology and in the market. There are many fields involved, covering various industries of the national economy such as industry, agriculture, medicine, and military. At present, most of the main applications of machine vision are still concentrated in large-scale automated production. In general, these areas are very sensitive to cost, and there are still some limitations in capital investment. The current optical lens market, purchased from abroad, prices only increase; domestic production, because of the continuous upgrading of technology, the cost continues to increase, the price has also risen accordingly. Therefore, in the future development process, the domestic machine vision market needs low-cost multispectral/cleartran and standard CVD ZnS optics. In the process of catching up with the international advanced level, cost-effective optical lenses are more suitable for the Chinese machine vision market.
