“…In contrast to the paraxial method, since the lens module method employed in this study involves lots of physical quantities of the optical system, some of them can be manipulated directly by using lens modules. Several lenses have been designed and evaluated by lens modules (Stavroudis and Merecado, 1975;Kuper and Rimmer, 1988). Choose a suitable structure in references first, optimizes and adjusts until to meet the requirements.…”

The compact, slim and high pixel mobile phone camera is highly demanded with the development of mobile phone, especially the thinner and thinner request of people. To satisfy this need, a mobile phone lens system composed of 1 glass spherical lens and 3 plastic aspheric lenses was designed with Code V. The F-number was 2.85 and FOV was 61°, the effective focal length and back focal length are 5 and 0.468 mm, respectively. A 1/3.2 inch 8 mega-pixel CMOS made by APTINA was taken as the image sensor of the lens assembly, whose pixel size is 1.4 µm and the limiting resolution was 357 lp/mm. The design results shown that the M TF value was more than 0.2 within most fields of view at the Nyquist frequency and more than 0.5 at the 1/2 Nyquist frequency, the maximum distortion was 0.66%. It shows that the lens has good performance and meets practical requirements.

“…For thick lenses, the famous optical design program Code V provides the virtual "lens module" [3], using a variation of the mock ray tracing scheme by Walther [4][5][6], to evaluate the system aberrations influenced by the conceptual lens modules with specific first-order and aberration properties. The first-order parameters of a lens module are specified by the overall module length, the focal length, the front focal distance (MFF), and the back focal distance (MBF).…”

Two optical lenses with the same focal length but different lens thicknesses and principal plane locations can provide equivalent first-order optics on imagery if the marginal and chief ray heights and slope angles at their principal planes are equal, resulting in the same system magnification, object and image distances. In this paper, we will prove that if these lenses have the same primary aberrations (including Seidel aberrations, chromatic aberrations, and secondary spectrum) corresponding to the same marginal and chief rays then they must have the same new aberrations for any same new rays. This theorem is useful when designers would like to redesign a lens group in a system. The influence on the movements among lens groups, the special aberration properties of plane parallel plates, and afocal lens groups are also discussed.

“…It is difficult to judge if the solutions satisfy all the requirements for the zoom system [1][2][3][4][5]. Contrary to the paraxial method, since the lens module method employed in this study involves lots of physical quantities of the optical system, the first-order and thirdorder aberrations can be manipulated directly by using lens modules [6][7]. Several zoom lenses have been designed and evaluated by lens modules [8][9][10][11][12].…”

This study presents a new design method for a zoom lens, in which real lens groups are designed successively to combine to form a lens modules zoom system. The lens modules and aberrations are applied to the initial design for a four-group inner-focus zoom system. An initial design with a focal length range of 4.2 to 39.9 mm is derived by assigning the first-order quantities and third-order aberrations to each module along with the constraints required for optimum solutions. After obtaining the lens module zoom system, the real lens groups are successively, not separately, designed to get a zoom lens system. Compared to the separately designed real lens groups, this approach can give a better starting zoom lens and save time. The successively designed groups result in a zoom system that satisfies the basic properties of the zoom system consisting of the original lens modules. In order to have a slim system, we directly inserted the right-angle prism in front of the first group. This configuration resulted in a compact zoom system with a depth of 12 mm. The finally designed zoom lens has an f-number of 3.5 to 4.5 and is expected to fulfill the requirements for a mobile zoom camera having high zoom ratio of 10x.
