Lens: Domestic enterprises compete in the low-end market, and the high-end market gradually begins to lay out

CPCI-AC-6U-500 Lens quality directly affects the overall performance of the vision system and is the most critical imaging component in the machine vision system. The mirror head is the starting point of the information acquisition and transmission process of the subject in the machine vision system, which is equivalent to the lens of the human eye. The role of the lens is to focus the target’s light radiation on the photosensitive surface array of the camera chip. The parameters of the lens include focal length, field of view, working distance, resolution, depth of field, etc. The actual selection needs to consider the match between the camera and the image sensor. With the rapid development of CMOS image sensor technology, the sensor has smaller pixels, so it needs a higher resolution lens. In addition to resolution, all lenses are also subject to a certain amount of spatial distortion, when the lens stretches or compresses the image in a non-linear manner, making accurate measurement of the entire sensor very difficult. The high distortion problem of traditional lens makes the application of telecentric CPCI-AC-6U-500 lens come into being. The unique parallel optical path design of the telecentric lens can correct the parallax of the traditional industrial lens, and the obtained image magnification will not change within a certain range of object distance. It has the characteristics of high resolution, ultra-wide depth of field and ultra-low distortion, and is popular in the field of precision detection.

The global industrial lens market is growing steadily, and the Chinese market continues to expand at a high speed. From 2016 to 2019, the global industrial lens market grew from $1.08 billion to $1.20 billion, CPCI-AC-6U-500 CAGR3.4%; The size of China’s industrial lens market grew from 230 million yuan in 2016 to 700 million yuan in 2019, CAGR45.9%, China’s industrial lens market is expanding rapidly beyond the growth rate of the global market, the high-speed expansion is mainly behind the continuous improvement of related production and development processes, and the quality and efficiency of boost lens production continue to improve. For example, the development of coating technology has improved the yield of the lens, and the input of the automatic assembly machine has changed the assembly link from manual to automatic assembly, improving the assembly efficiency and product stability.

Domestic enterprises rely on price advantages and mass production capacity to compete for low-end products, and the high-end market has begun to gradually layout. At present, China’s industrial lens market is mainly dominated by foreign veteran lens manufacturers, CPCI-AC-6U-500 including Germany Schneider, Germany Carl Zeiss, the United States Navitar, Japan KOWA, etc. These foreign enterprises have strong technology accumulation, brand influence, and obvious advantages in the high-end industrial lens market, but the general product price is high, and the application of the Chinese market is insufficient. Since 2009, domestic enterprises have gradually begun to make efforts, but most of the domestic industrial lens manufacturers are relatively small in size, mainly cutting into the low-end market, and competing with foreign brands with cost-effective advantages, such as Dongguan Pumis. At the same time, some domestic manufacturers such as Dongzheng Optical have the strength to provide a full range of industrial lenses, and are actively laying out the high-end product market, and Haikang and Dahua also have the production capacity of industrial cameras. At present, there is still a gap between domestic manufacturers and foreign veteran manufacturers in lens production technology, but they have basically been able to meet the basic needs of the visual system.
