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 ...

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 ...

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 ...

A team of researchers at the University of Delaware (UD) have successfully tested a lens built at microchip scale on top of a silicon wafer, using specialised thin metasurface materials. This could be ...

Key trends in the automotive industry involve producing safer vehicles for people inside and outside the car—smarter technology for more comfort and ease of use and toward cars that are “greener” or ...

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 ...
