"WebA zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (see prime lens).. A true zoom lens (or optical zoom lens), also called a parfocal lens, is one that maintains focus when its focal length changes. Most consumer zoom lenses do not maintain … " - Optical relationships definition in design

WebJun 7, 2010 · They are used routinely for a multitude of applications that require splitting of an optical field into two coherent but physically separated parts (and vice versa). Even though our focus is on the nonlinear optical phenomena in fiber couplers, theory developed here applies to all directional couplers. WebAn optical encoder is a digital (or pulse-generating) motion transducer. Here, a light beam is intercepted by a moving disk that has a pattern of transparent windows. The light that passes through, as detected by a photosensor, provides the transducer output.

WebIntroduction to Modulation Transfer Function. When optical designers attempt to compare the performance of optical systems, a commonly used measure is the modulation transfer function (MTF). MTF is used for components as simple as a spherical singlet lens to those as complex as a multi-element telecentric imaging lens assembly.
