Abstract

Abstract. Microscopy is very important in research and industry, yet traditional optical microscopy suffers from the limited field-of-view (FOV) and depth-of-field (DOF) in high-resolution imaging. We demonstrate a simultaneous large FOV and DOF microscope imaging technology based on a chip-scale metalens device that is implemented by a SiNx metalens array with a co- and cross-polarization multiplexed dual-phase design and dispersive spectrum zoom effect. A 4-mm × 4-mm FOV is obtained with a resolution of 1.74 μm and DOF of 200 μm within a wavelength range of 450 to 510 nm, which definitely exceeds the performance of traditional microscopes with the same resolution. Moreover, it is realized in a miniaturized compact prototype, showing an overall advantage for portable and convenient microscope technology.

用于宽视场和景深成像的芯片级金属透镜显微镜

摘要显微镜在研究和工业中非常重要，但传统的光学显微镜在高分辨率成像中存在视场（FOV）和景深（DOF）有限的问题。我们展示了一种基于芯片级金属透镜器件的同时大视场和自由度显微镜成像技术，该器件由SiNx金属透镜阵列实现，该阵列具有共偏振和交叉偏振复用双相位设计和色散光谱变焦效应。A 4毫米 × 获得4毫米视场，分辨率为1.74 μm，自由度为200 μm，在450至510 nm的波长范围内，这绝对超过了相同分辨率的传统显微镜的性能。此外，它是在一个小型紧凑的原型中实现的，显示了便携式和方便的显微镜技术的整体优势。
