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. WebA ‘crystal lens equation’ (CLE) was indeed formulated by Chukhovskii & Krisch (1992) for the focusing properties of a ISSN 1600-5775 cylindrically bent crystal plate diffracting monochromatic X-rays or neutrons, in Laue (transmission) or Bragg (reﬂec- … 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). hollow creek movie trailer
