However, the days of bulky, expensive telescope lenses could soon be coming to an end thanks to the team's new flat lens measuring less than a millimeter thick. that has been developed by a team ...

Power of a Diffraction Space Telescope. This new lens design makes it possible to rethink how a space telescope might be built. In 2019, our team published a concept called the Nautilus Space ...

A new way to control light. Traditionally, optics relied on bulky lenses to bend light. Whether in a smartphone or a telescope, thick glass has long been essential for creating sharp images. But ...

The study, “Color astrophotography with a 100 mm-diameter f/2 polymer flat lens,” appeared on Feb. 3 in Applied Physics Letters.This research was supported by the Defense Advanced Research ...

But when telescopes must focus light from galaxies millions of light-years away, the bulk of their lenses become impractical. That's why observatory and space-based telescopes rely on massive ...

Aperture Size: The lens or mirror’s diameter in a telescope, known as the aperture, is a critical factor. A larger aperture allows more light to enter, producing brighter and clearer images.

The Sevunscope is intended to bring that same sort of upgradability to consumer telescopes. If you own a DSLR camera, you can simply buy more lenses as your needs dictate, instead of having to buy ...
