Cold Processing Technology of Optical Lenses

At present, the pattern of global optical cold processing and consumer digital optoelectronic product production capacity shifting to China has basically taken shape, making China a global production and processing hub for optoelectronic products.

In terms of regional distribution, most of the optical cold processing production capacity is concentrated in the Pearl River Delta and Yangtze River Delta regions. South China has become a world - class digital camera production base, and it is also a region with a relatively large scale of optical cold processing production capacity and a high degree of industry concentration worldwide. The international division of labor and industrial transfer in optical cold processing and optoelectronic products have provided good development opportunities for enterprises in the industry, and the competition among enterprises will further intensify.

Among downstream products, the demand for optical cold processing products from digital camera products accounts for nearly 40% of the total demand. Therefore, the competition for orders from digital camera manufacturers has become the focus of competition among enterprises in the industry. Currently, most large - scale digital camera production enterprises are Japanese manufacturers, such as Canon, Minolta, Olympus, Sony, Fuji, etc. They generally adopt a qualification certification system for optical cold processing enterprises: they focus on examining the delivery time, product quality, production capacity scale and management level of candidate enterprises, and conduct a comprehensive score. After an enterprise obtains qualified certification, it can generally win relatively stable long - term orders from Japanese manufacturers.

With the continuous introduction of new optical products and the increasing sophistication of optical technology, the scope of application has been continuously expanded. From early traditional cameras, telescopes, microscopes, scanners, fax machines, etc., to current optoelectronic image information processing products such as digital cameras, camera phones, projectors, rear - projection TVs, all use a large number of optical component products.

Since 2001, consumer digital optoelectronic products represented by digital cameras and camera phones have risen rapidly and grown at an extraordinary speed, directly driving the optical cold processing industry into a cycle of high - speed growth and prosperity. With technological progress and consumption upgrading, the prices of consumer digital optoelectronic products have been continuously reduced and their functions have been continuously improved, and the overall market capacity will still maintain growth. The sales volume of traditional optical products represented by traditional cameras has been gradually shrinking, and the demand for optical component products from consumer digital optoelectronic products has become a decisive force driving the continued growth of the optical cold processing industry.

Among the above - mentioned consumer digital optoelectronic products, multi - function printers (with relatively low sales in Chinese Mainland), DVD players, and laser printers have relatively low demand for optical glass spherical lenses, and their growth will be relatively stable in the future; Camcorders have a low penetration rate in China and are consumer upgrading products, but their growth is expected to be limited in the short term.

Digital cameras, camera phones and projectors have a great impact on the demand for optical cold processing products (such as optical glass spherical lenses, aspherical lenses, lens modules, etc.). New demand growth points also include rear - projection TVs, digital single - lens reflex cameras, etc. Analyzing the future development trends of these segmented markets is helpful for judging the development prospects of the optical cold processing industry.
