Breakthrough in transparent optical ceramics: High-refractive-index transparent ceramic lenses developed by Songshan Lake Laboratory have completed pilot industrial production with refractive indices ranging from 1.8 to 2.3, exceeding the upper limit of traditional optical glass. The products are applied in ultra-thin mobile phone camera modules.
Significant capacity expansion of domestic polarizer production: Shinwha Optoelectronics (Shanshan Group) has put its ultra-wide-width polarizer production line into operation. Domestic polarizers account for over 45% of the global market share, yet upstream optical PVA base film still relies on imports from Japanese enterprises.
