WebNov 1, 2015 · A resolution of 22 nm half-pitch (hp) on the mask side, corresponding to 5.5 nm hp on the wafer side in a 4× lithography system, has been demonstrated for the 0.625 4× NA lens. Optical resolution describes the ability of an imaging system to resolve detail, in the object that is being imaged. An imaging system may have many individual components, including one or more lenses, and/or recording and display components. Each of these contributes (given suitable design, and … See more Resolution depends on the distance between two distinguishable radiating points. The sections below describe the theoretical estimates of resolution, but the real values may differ. The results below are based on … See more An imaging system running at 24 frames per second is essentially a discrete sampling system that samples a 2D area. The same limitations described by Nyquist apply to this system as to any signal sampling system. All sensors have a … See more There are two methods by which to determine "system resolution" (in the sense that omits the eye, or other final reception of the optical information). The first is to perform a … See more The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.
