Fabrication Technique Brings Metasurface Production Closer
GOTHENBURG, Sweden, June 15, 2020 — Researchers from Chalmers University of Technology have developed a new method of creating metasurfaces, which could bring mass production of ultrathin lenses closer to reality. Metasurfaces consist of a multitude of interacting nanoparticles that...
Autofocus Lens Mimics the Eye
TRONDHEIM, Norway, Oct. 14, 2011 — Making cell phone cameras work more like the human eye may help overcome limitations in low light sensitivity and focusing. Most cell phones today have built-in cameras, but these are not equipped with autofocus capabilities, as are ordinary...

SAN JOSE, Calif., May 7, 2009 – Subsidiaries of Tessera Technologies Inc. will acquire certain assets of Israel-based Dblur Technologies Ltd., a developer of software lens technology for cell phone cameras and other imaging applications. Financial details were not...
Liquid lens: water + sound = fast focusing
TROY, N.Y. – An adaptive liquid lens that is powered by water, sound and surface tension can capture 250 pictures per second using very little energy, and its ability to focus extremely quickly (in 0.01 seconds) makes it promising for use in cell phone cameras,...
PerkinElmer Awarded Xenon Flashlamp Orders
Jul 24, 2007 — PerkinElmer Inc. of Waltham, Mass., said it has received multiple orders for mobile-phone flash assemblies using its Xenon-based flash technology, and that it will ramp production in the next year. Xenon flash provides intense but short light...
Liquid Used as Lens for Miniature Cameras
Oct 1, 2004 — As cell phone cameras and other optical devices become smaller and smaller, the lenses become more complex. When the surface-to-volume ratio increases, so does friction, making it difficult to fabricate tiny lenses with moving parts. As a possible...
