Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on amateur telescopes. Engineers and astronomers at the University of Utah have ...

As the lens gets bigger, it needs more space aboard a telescope and stronger support structures. As a result, the weight and size of such telescopes reach a level where the payload capacity ...

Engineers and astronomers at the University of Utah have designed a unique new kind of telescope lens: a flat lens with microscopic etchings to refract light. If the concept can be scaled up ...
