Higher-order aberrations were corrected by around 75% in eyes with keratoconus fitted with Zenlens Chroma HOA, according to data presented at the Global Specialty Lens Symposium.“Patients with ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Towards the end of the 19th century, Abbe and Rayleigh formulated the principles of optical diffraction that limits the resolution of optical instruments in the far-field where the distance between ...

Not an aberration: schematic drawing of the metalens (left), which is made of tiny titanium waveguides. The drawing on the right is of a single waveguide. (Courtesy Boubacar Kanté) A new type of ...

Given that vintage glass is not only holding its value but getting more expensive, digitally recreating some of that classic look digitally is a sound option. It also comes with an undo button. When ...

Researchers from the Optics Group at the Universitat Jaume I in Castellón have managed to correct in real time problems related to image aberrations in single-pixel microscopy using a recent ...

Ideal for laser-focusing applications, 10 to 30-mm Gradium Series lenses use glass with an axial gradient that changes the lens index by as much as 0.15 from front to back to correct aberrations. Two ...
