High refractive index and low birefringence polymers for XR applications

XR devices require advanced optical lenses to achieve the trends like miniaturization, weight reduction and higher performance (high resolution and wide field of view). To achieve these goals, high-performance optical materials are required. Iupizeta EP is a specialty polycarbonate resin specifically developed for optical lens applications, offering high refractive index, high transmittance, and low birefringence. Iupizeta EP has gained a significant market share in the field of smartphone camera lenses. Through our expertise in controlling optical properties with distinct techniques of molecular design, Mitsubishi Gas Chemical have developed new optical materials for XR lens systems. This optical material maintains existing performance while offering superior moldability and ultra-low birefringence. This innovation allows for high dimensional accuracy and low birefringence even in thick or complex shapes, significantly enhancing flexibility in product development. This material is expected to refine the next-generation XR devices and significantly change the conventional concept of XR devices.
