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. 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 … desk coin pusherWebJun 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).
