“…Our previous work presented in 2017 provided a simple but efficient approach to adopt microsphere lens in an ordinary microscope. With a 3D printed objective adaptor, the microsphere can work synchronously under objective to realize largearea scanning imaging [24]. Similar work was also demonstrated from H. Yang's previous paper [25].…”

Microsphere-based subwavelength imaging technique was first demonstrated in 2011. After nearly a decade of efforts, such technique has spawned numerous interests in fields such as laser nano-machining, imaging, sensing and biological detection. For wider industrial scale application of the technique, a robust, low-cost objective lens incorporating microsphere lens is highly desired and sought by many researchers. In this work, we demonstrate a unibody microscope objective lens formed by tipping a high-index microsphere onto a Plano-Convex lens and subsequently fitting them into a conventional objective lens. We call such new objective the Plano-Convex-Microsphere (PCM) objective, which resembles the appearance and operation of an ordinary microscope objective, while providing super-resolving power in discerning subwavelength nanoscale features in air condition. The imaging performance of PCM-objective along with the working distance has been systematically investigated. With the assistance of scanning process, larger area imaging is realized. The PCM-objective can be easily adaptive to many existing microscope systems and appealing for commercialization.

“…These processes are interlinked and coupled and complete model is still missing today. Most existing theoretical studies are based one or two processes above, leading to incomplete conclusions and debates [22,33,31,34,35,18,36,24,37,38,19,[39][40][41].…”

Recently, imaging by microspheres and dielectric particle-lenses emerged as a simple solution to obtaining super-resolution images of nanoscale devices and structures. Calibrated resolution of ~λ/6 -λ/8 has been demonstrated, making it possible to directly visualize 15-50 nm scale objects under a white light illumination. The technique has undergone rapid developments in recent years, and major advances such as the development of surface scanning functionalities, higher resolution metamaterial superlens, biological superlens and integrated biochips as well as new applications in interferometry, endoscopy and others, have been reported. This paper aims to provide an overall review of the technique including its background, fundamentals and key progresses. The outlook of the technique is finally discussed.

“…Subsequently, the research focus shifted towards applications 17 – 26 , but in these papers super-resolution was achieved typically over a very small area that was comparable to the size of the used micro-object. Recently, it was demonstrated that the super-resolved area can be extended by various scanning methods 27 – 31 , including the super-resolution imaging ability of dielectric microspheres that were used in an atomic force microscopy (AFM) setup 32 , 33 . This technique extended the field-of-view of the imaging system, but also carried the drawbacks of an AFM system, namely the extreme sensitivity on vibration, requiring a dedicated setup.…”

We report dielectric microsphere array-based optical super-resolution microscopy. A dielectric microsphere that is placed on a sample is known to generate a virtual image with resolution better than the optical diffraction limit. However, a limitation of such type of super-resolution microscopy is the restricted field-of-view, essentially limited to the central area of the microsphere-generated image. We overcame this limitation by scanning a micro-fabricated array of ordered microspheres over the sample using a customized algorithm that moved step-by-step a motorized stage, meanwhile the microscope-mounted camera was taking pictures at every step. Finally, we stitched together the extracted central parts of the virtual images that showed super-resolution into a mosaic image. We demonstrated 130 nm lateral resolution (~λ/4) and 5 × 105 µm2 scanned surface area using a two by one array of barium titanate glass microspheres in oil-immersion environment. Our findings may serve as a basis for widespread applications of affordable optical super-resolution microscopy.
