Scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens ...

Using 3D printing and porous silicon, researchers at the University of Illinois Urbana-Champaign have developed compact, visible wavelength achromats that are essential for miniaturized and ...

(Nanowerk Spotlight) Planar optical components are crucial to realize miniaturized optical systems and integrated optoelectronic devices. In particular, metasurfaces – 2D structured materials with ...

Techspec MgF2-coated achromatic lenses from Edmund Opticsnow include F/1 versions and smaller diameters. Comprising two opticalcomponents cemented together to form an achromatic doublet, ...

An achromatic cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point-focusing spot ...
