When used in an infinite conjugate state, their spherical aberration is minimal. Achromatic lenses are suitable for a variety of applications such as fluorescence microscopy, image relay, detection, ...

Plano- convex cylindrical lenses are typically used for illumination of slit ... while the cylindrical lens acts in only one direction on the incident light. A typical application is to shape a ...

By carefully placing nanostructures on a flat surface, researchers at Linköping University, Sweden, have significantly ...

By carefully placing nanostructures on a flat surface, researchers have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for ...

In contrast, we have unambiguously shown both the convex and concave functionalities ... The dual-polarity plasmonic flat lens opens an avenue for new applications of phase discontinuity devices ...

These lenses are either convex - converging light, which magnifies an object, or concave, where light diverges making an object smaller. However, this new lens is 40 nm thin on a flat glass surface .

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.

Several other lenses are demonstrated, including a cylindrical convex lens, but these are only planoconvex lenses, or lenses that are flat on one side. Biconvex lenses can be constructed by gluing ...

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...
