Spherical crystal lens
WebNov 13, 2014 · Colloidal photonic crystals (PhCs), periodically arranged monodisperse nanoparticles, have emerged as one of the most promising materials for light manipulation because of their photonic band gaps (PBGs), which affect photons in a manner similar to the effect of semiconductor energy band gaps on electrons. WebWhen people start shopping for watches, the type of watch glass can cause a lot of confusion. One of the most common sources of confusion is sapphire because it is also used in jewel bearings in the watch …

WebWe demonstrate a tunable focus liquid crystal (LC) lens by sandwiching a homogeneous LC layer between a planar electrode and a curved electrode. The curved electrode which is made of conductive polymer has parabolic shape with a large apex distance. Such design dramatically reduces the phase loss which leads to a short focal length (~15 cm).

WebFeb 7, 2024 · This spherical lens is ultra clear, polished, and hardened to a scratch-free surface to get the smoothest and clearest pictures possible. Each Lens ball is 100% … Lenses do not form perfect images, and a lens always introduces some degree of distortion or aberration that makes the image an imperfect replica of the object. Careful design of the lens system for a particular application minimizes the aberration. Several types of aberration affect image quality, including spherical aberration, coma, and chromatic aberration.
