Chip-scale metalens array for polarization-embedded metalens imaging device (PMID) and compact portable microscope system (PMS).

Caption

Chip-scale metalens array for polarization-embedded metalens imaging device (PMID) and compact portable microscope system (PMS): (a) chip-scale metalens array integrated in the CMOS image sensor with zoom-in images; (b) the PMS with compact size of 3×3.5×4 cm3 by integrating the PMID, sample holder, LC-polarizer and LED source; and (c) wide-field microscopic image for a bio-specimen of the pine stem cross section covering a 4×4-mm2 FOV with 1.74-μm resolution. The blue box area is the recorded FOV of a traditional microscope.
