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 ...

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 ...
