For the first time, a flat telescope lens has been produced that represents colors accurately, offering a way to make less bulky lenses that could be sent into space cheaply. The first telescopes used ...

For centuries, cameras and telescopes have relied on curved glass or plastic lenses to bend light and bring images into focus ...

While this method does create a lightweight and compact lens, it comes with a tradeoff: it can’t produce true colors. Rather than bending all of the wavelengths of visible light at the same ...

The study, "Color astrophotography with a 100 mm-diameter f/2 polymer flat lens," appears in Applied Physics Letters. This technology could transform astrophotography imaging systems ...
