Miniaturization of electronics has reached such proportions that it is now high-quality camera is inserted into a smart phone. Until recently, the main deterrent to further decrease in size was the photographic lens - part of the chamber through which the light is focused on the sensor. Make it a miniature, while maintaining the functionality was not possible.
Scientists from Harvard University Federico Capasso, Frachesko Aeta and Patrick Genyuvet from the Harvard School of Engineering and Applied Sciences (SEAS) have achieved a breakthrough by using the ultra-thin silicon wafers, which they covered with a gold layer thickness in the nanometer.
A portion of the gold layer was removed to leave a lot of structure in the shape of the letter V, which are located across the surface of the lens, according to Gizmag. The scientists claim that they have created lenses are extremely easy to make, so that any problems in the implementation of the production does not occur. They believe that the market will soon master the technology developed by them. We've both. If a cheap place, so once the market.
