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.
