Recently, SZJB Optoelectronics Technology Group, a leading manufacturer of precision filters and functional optical lenses in China, issued an announcement stating that the company will invest 710 million yuan to build a high-end filter project
SZJB is an innovative optoelectronic component manufacturing enterprise that integrates material development, film system design, coating process and process control based on the development and application of photoelectric thin film technology. Since its establishment, Keihin Optoelectronics has insisted on driving and leading each other with dual-core technology innovation and scene application, and constantly innovating vacuum coating technology, from glass substrate coating to resin substrate coating, and then to direct coating on the surface of semiconductor chips from the substrate; at the same time, it continues to expand New application areas, from high-performance reflective film components and functional film components,infrared cut filters for smartphones, camera module components, filters for digital SLR cameras, optical reflective lenses and filters for projectors/scanners, high reflective lenses for solar energy, and liquid crystal ITO conductive film lenses… for office digital equipment to optical film components such as cameras, photosensitizers, and 3D recognition for smart equipment, and then further into the field of optical and semiconductor chip integration (wafer coating ), optics and medical integration field.

Based on optoelectronic thin film technology, SZJB extends to upstream raw material development and downstream application fields, continuously innovating and upgrading, and becoming a leading domestic innovative optoelectronic component manufacturing enterprise integrating material development, film design, coating process and process control. . After nearly 30 years of development and practice of optoelectronic thin-film components, SZJB is currently at the leading level in the industry in film design and coating technology.
Its products are precision optoelectronic thin film components, mainly including imaging and photosensitive optical film components, high-performance reflective film components and conductive film and other functional film components. Imaging and photosensitive optical film components are vapor-deposited infrared cut-off film components. According to the substrate, they can be divided into white glass IRCF, blue glass IRCF, and resin IRCF. The product forms include small pieces, medium pieces and components.
IRCF (infrared cut filter) is an important component of the camera module. With the continuous improvement of the requirements of "high imaging quality" and "lightness and thinness", the optical substrate has changed from the first-generation white glass of the reflective type to the absorbing type. The second generation of blue glass has now been developed to the third generation of absorbent resin.
From 2018 to 2020, one of SZJB's main products is IRCF for imaging and photosensitive components, with resin IRCF accounting for the largest share of revenue. Resin IRCF is a new generation product, which has the characteristics of "light, thin and firm" and excellent optical properties, but the coating process is difficult and represents the industry's leading level. At present, while the industry is still focusing on the production of 0.21mm-thick glass IRCF, SZJB has steadily mass-produced 0.11mm resin IRCF, 0.075mm resin IRCF has also achieved mass production, and is developing 0.05mm resin IRCF. In recent years, thanks to the wide application of high-pixel products such as smart phone cameras, the market demand for resin IRCF has increased year by year. SZJB produces resin IRCF with the technical advantages of stable mass production of high-quality products, and has a high reputation in the market. The number one in China.
SZJB has passed the qualified supplier system certification of many internationally renowned optoelectronic component manufacturers, such as OFILM, Sunny Optical, Qiuti Technology, Samsung Electro-Mechanics, AAC Technology, Lianchuang Electronics, Tongxingda and other camera module manufacturers,as well as SONY, JSR, Konica Minolta, Ricoh, Toshiba, Panasonic, Olympus, AGC, NEC, Honeywell and other optoelectronic product manufacturers.
