Using 3D printing and porous silicon, researchers at the University of Illinois Urbana-Champaign have developed compact, visible wavelength achromats that are essential for miniaturized and ...

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 eye boasts ...

(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 ...

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 ...

Using an approach that combines 3D printing, silicone molding and a UV curable clear resin, researchers fabricated an inexpensive lenslet array, which they used for super-resolution imaging in a ...

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 ...
