Scientists create a tiny, flexible lens modeled on insect eyes
Science seems obsessed with creating tiny objects that can do big things. Like a team at the University of Wisconsin-Madison which has created a new microlens with a 170-degree field of vision. Modeled after an insects multi-faceted eye, the flexible lens is roughly the size of a pinhead. Where typical lenses refract light, this one focuses using diffraction, which bends it as it passes over the folded barrier. Each of these bendable structures look like bullseyes because the lens is made up of both light and dark regions. The distance between these concentric circles determines how far the lens can see and the best part is, because they're flexible, the field of vision can be easily altered.
Physicists develop microlens with earth-shatteringly short focal length
It's hard to say when we, the consumers, will actually see any real benefit from the latest noteworthy discovery from Northeastern University, but we can only imagine that Srinivas Sridhar and team aren't wasting any time moving things forward. Said crew has recently created a "new microlens that focuses infrared light at telecommunication frequencies," and if you're looking for specifics, it can focus an infrared beam to a spot just 12-micrometers away from the surface. The science behind the discovery is probably only digestible by those that understand rocket science, but the long of short of it is this: the "research shows that it is possible to create smaller, ultra-compact infrared optical components that can be integrated into existing semiconductor technologies while not sacrificing image quality." Now that's something even the layman can appreciate. [Via Physorg]
