High‐Fidelity Far‐Field Microscopy at λ/8 Resolution (Laser Photonics Rev. 16(11)/2022)

Far-Field Super-Resolution Microscopy In article number 2200307, Qiaofeng Tan and colleagues propose a high-fidelity far-field microscopy with spatial resolution at λ/8. Assisted by two-dimensional multi-level diffractive optical element, the efficiency least increases two orders in contrast to reported superoscillatory, which ensures of 69 nm for complex samples high-fidelity.
