This breakthrough, which the team is calling the first broadband transformation optics metasurface lens, may lead to the creation of new types of antennas that are flat, ultra low-profile or conformal ...

Aspheric lenses possess a variable radius of curvature, allowing for a gradual change in shape that corrects optical aberrations effectively. Aspheric lenses provide superior aberration control, ...

Spherical lenses are optical lenses with curved surfaces which converge or diverge light rays, thus forming a real or virtual image of an object. They are also known as singlets. Before selecting a ...

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

Visible spherical lenses are optical components designed to operate within the visible spectrum, which ranges from 380 to 750 nm. These lenses are crafted to focus or disperse light through their ...
