title: Paraxial analysis of three-component zoom lens with fixed distance between object and image points and fixed position of image-space focal point.
abstract: This work performs an analysis of basic optical properties of zoom lenses with a fixed distance between object and image points and a fixed position of the image-space focal point. Formulas for the calculation of paraxial parameters of such optical systems are derived and the calculation is presented on examples.
