A newly developed polarizer-embedded metalens enables a compact, portable microscope system that efficiently obtains wide-field, noise-free, high-resolution images.
As reported in Advanced Photonics in July 2022, researchers from Nanjing University developed a polarizer-embedded metalens imaging device (PMID). The PMID is implemented based on a silicon nitride metasurface mounted on a CMOS image sensor with a fixed circular-polarization filter inserted between the two. It eliminates background noises, and even enables zoom-in imaging.
