Flat Surface Lens Overcomes Limitations of Conventional Optics

Facebook Twitter LinkedIn Email Comments

An increased aperture-to-depth ratio and a smaller lens stack open possibilities from telescopes to camera lenses in smartphones.

ELIZABETH HOWELL, Space and Science Journalist

The telescope has been used for more than 400 years. Although there have been many designs created for looking at distant objects, there is a fundamental weakness with the lens system. By necessity, telescopes use curved lenses — which are prone to aberrations. For the first time, a novel flat surface lens system offers the potential for better resolution from a significantly more compact size. The flat lens system gathers about 27 percent more light than a comparably sized curved aperture with squared corners. The design increases the aperture-to-depth ratio in devices that...Read full article
