Design theory and practice of using three-lens glued element in depicting optical systems
The article presents an analytical overview of the methods of parametric synthesis of an element glued from three spherical lenses, which relates to the base modules of depicting optical systems of different scheme and functional purposes.The theoretical basis of the methodologies is the classical theory of lower orders of monochromatic and chromatic aberrations of the thin optical component.The application of the methodologies ensures the design of a three-lens gluedmonochromat, achromat and apochromat for various combinations of other aberration requirements.Using the results of the analysis of known optical systems, the fundamental possibility of using this module to solve non-trivial correction problems for both aperture and field aberrations is shown.The presented examples correspond to the basic applications of a three-lens glued element, classified by its location relative to the aperture and field apertures of the optical scheme and the correction problems to be solved.
