Study And Design Of The Zoom Lens System

Recent years,comply with the developing of zoom lens optics design theory and the perfect of machining technics,the kinds of zoom lens system become multiform,the quality of picture is improved,the zoom lens system could compare beauty with focus lens,so they are used in a great many of parts.In this condition,studying zoom lens design is very significance.This article is built on the information of domestic and overseas literature,first it introduces the history of zoom lens system,the style of each epoch,analyzing the theory of zoom,the characteristic of the zoom lens system,the class of zoom lens and all kinds of zoom lens characteristic,the law of zoom lens need to satisfy,all of these are service for the consequence by matrix theory.The flowing is my work which is also the innovation of this article:1,relay on experts' analyses of zoom lens system theory,using the Mastic deduce the zoom equation of one variety one compensate style's zoom lens system,solution the zoom equation in different the back focal distance,give the extreme point of zoom equation and analyze the singularity of the extreme point,prove that is a right war through several examples of the equation.2,relay on the characteristic of the two moveable group's zoom lens, give the form of the two moveable group's zoom lens though the Mastic.3,study the way of solving the multiple moving zoom optical system, According to compensate the last move group to keep the back focal distance for Fixed value,using the Mastic deduce the equation of multiple moving zoom optical system,and give a example of the multiple moving zoom optical system in especial condition.Prove the Mastic is suitable for the multiple moving zoom optical system.4,Consult the pat US07502171,using optics design software CODEV design a zoom lens system of one variety one compensate style's,compare with the pat,the system have less move groups,smaller distortion,and higher pixel characteristic.5,Consult the pat US07339745,using optics design software CODEV design a zoom lens system of one variety one compensate style's,compare with the pat,the system have cheaper glasses,smaller optical aberration and higher pixel characteristic,comparing the two designs express the characteristics of each other,it is help for selecting zoom lens system.Finally,give a summarize of the article,and combining with the knowledge which I have give a prospect of the zoom lens system's developing direction and the method of ameliorating the zoom lens system.
