Scientists have developed an impossibly thin telescope lens that addresses a key astronomical challenge in a new study funded ...

Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

Here's how an innovative flat lens could solve these problems for satellites and space-based telescopes. Understanding ...

ABSTRACT: We present an ab-initio study of the mechanical properties and spin-dependent Density of States (DOS) of the iron pnictide compound CaFe2As2 at ground state. Ground state energy calculations ...

Ordinary lenses refract different colors at slightly ... The paper is published in the journal Applied Physics Letters.

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 ...

I’ve been wearing contact lenses for over two decades; to find the best contact lenses for different vision needs, I tapped into my own experience and also relied on the expert insights of ...

\(power \ of \ a \ lens \ (D) = \frac{1}{focal \ length \ (m)}\) A lens has a power of -3.33 dioptres. Calculate the focal length and state what type of lens it is.

Scientists have long sought to unravel the mysteries of strange metals—materials that defy conventional rules of electricity ...

The new paper, “Color Astrophotography with a 100 mm-diameter f/2 Polymer Flat Lens” appeared on February 3, 2025, in Applied Physics Letters. Ryan Whalen covers science and technology for The Debrief ...
