Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

The function and use of micro-lenses mainly include focusing, imaging, and optical function enhancement in specific applications. Micro-lenses are small optical components that can accurately control ...

Developments in the manufacture of polymer micro optics are helping optical designers to meet the exacting tolerances that are required for miniaturized optical components and subsystems. Heidi Hall ...

Atomic force microscopy, laser ablation, and etching with a witches brew of toxic chemicals: sounds like [Zachary Tong] has been playing in the lab again, and this time he found a way to fabricate ...

(Nanowerk News) They number in the thousands, light striking the phalanx of lenses arrayed on a face in geometric pattern, the beams refracting through transparent mounds no wider than a hair. A fly’s ...

A team has created minuscule lenses that it can expand or contract in mere seconds -- modifying their magnification, focal length and other optical properties in the process. That on-the-fly ...

As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted attentions of both the academia and industry, due to its distinctive optical properties and ...

The unique structures of biological vision systems in nature inspired scientists to design ultracompact imaging systems. Researchers have made an ultracompact camera that captures high-contrast and ...
