Title The future development trend of optical lenses
Description According to a survey of optical lenses, 52 users and 8 manufacturers were surveyed, 55% of which were from Europe, 23% from North and South America, 22% from Asia/Middle East, and held in Stuttgart. The results of the survey were announced at the VISION2016 conference. Europe ranks among the best in terms of procurement and production, with a market share of 62% and 43% respectively. Manufacturers are also producing in Asia (13%) and the US (6%). After Europe, Asia and the United States have the same strong purchasing market, each occupying 28% of the market. Compared with 2015, the US market share in production fell to 28%, which may also be affected by the small number of vendors participating in the survey in North and South America. Optical lens manufacturers say that from a sales point of view, measurement and logistics account for 50% and 13% respectively; production automation and quality assurance applications each occupy 63% of the market; medical diagnostics and scientific applications also occupy A 38% market share. Survey data from large size YVO4 laser crystal users also showed similar results: 48% of cameras were used in the automation field, 46% for quality assurance applications, 40% for measurement and 29% for scientific applications. Medical diagnostic applications account for 10% of user camera deployments. Transportation applications (including vehicle assistance systems) are also an important market for manufacturers, but for users, this market is not as important. As in previous years, camera manufacturers and system developers have seen continued growth in the image processing and machine vision industries, with 90% of users planning to roll out or replace existing equipment in the next two years. Camera pricing For the medium-priced high precision YVO4 laser crystal production ratio between 150-650 US dollars, in the manufacturer's production roadmap, it has steadily dropped from as high as 70% in 2014 to 44%, indicating that the price has passed the previous years. After a continuous decline, it has been relatively stable. For low-cost cameras below $150, the manufacturer's production ratio and user purchase ratio are 26% and 11%, respectively, and the importance is relatively low. Compared with 2015, high-priced cameras have dropped by 12 percentage points from $650/$1,000/$3,000 (see Figure 1). Therefore, for small camera manufacturers, producing customized cameras for specific applications seems to be a strong selling point and market advantage. CMOS compared with CCD As Sony stopped producing CCD image sensors, users have witnessed tremendous growth in the performance of companies such as ON Semiconductor, which currently accounts for 29% of the market. In last year's study, the decline in Sony users and manufacturers' expectations was not realized, and 32% of camera manufacturers still rely on Sony. In the next two years, Sony is expected to return to its market share before the announcement of the CCD shutdown: 37%. Compared with 2015, more users chose Sony in 2016, and the proportion of users increased from 35% in 2015 to 53% in 2016. Camera manufacturers point out that CMOS technology accounts for 85% of camera sales. Camera users are expected to reach this level of purchase in the next two years. Today, 51% of users use CMOS, but this percentage is expected to grow to 83% soon. With the gradual replacement of CCD technology, e2v will benefit from camera manufacturers (from 3% to 12%) and custom sensors (from 4% to 19%), both of which have shown the same positive prediction. In 2015, about 30% of users used sensors below 1 million pixels, but in 2016 this percentage dropped to only 10%. The use of 1 million pixel sensors has dropped significantly, resulting in an increase in usage of 1 to 3 million pixel products (up 10%), 3 to 5 million pixel products (up 2%), and 500 to 10 million pixel products (up 3%). In the next two years, manufacturers and users are expected to focus their applications on applications with frame rates between 25 and 60 fps. At the same time, applications with frame rates in excess of 100fps (user-oriented: 13% growth) and 200fps (for manufacturers: growth of 14%) began to increase significantly compared to 2015. According to survey data from wholesale YLF laser crystal manufacturers, GigE Vision is currently the most popular interface standard (33%), followed by Ethernet (15%). Compared with 2015, the proportion of the high proportion of Ethernet interface standards has declined in the past due to the low participation rate in the United States. Both camera manufacturers and users expect USB 3.0 and GigEVision to experience rapid growth with market growth rates of 8% and 10% respectively. Today, more than 75% of manufacturers and 60% of users believe that 5GB or more of bandwidth becomes critical. For interface selection for high-speed applications, feedback from camera manufacturers: 50% of manufacturers believe that USB 3.1 is an important interface for high-speed applications; 38% of manufacturers believe that 10GigE is ideal for high-speed applications. Let's take a look at feedback from users: 44% of users support high-speed transmission through 10GigE; and the proportion of users who support high-speed transmission via USB3.1 is 37%.
