PAGE III PAGE IV 一种三片型照相物镜的设计 摘 要 照相物镜的作用是把外界景物成像在感光底片上,使底片曝光产生景物象。三片型照相物镜是目前很多照相物镜的基础,很多物镜都是基于三片型照相物镜发展而来的。三片型照相物镜最初是将两个完全一样凸透镜分别置于一个凹透镜两边,使其总光焦度为零,这样构成对称结构,可以完全消除场曲。而目前的三片型照相物镜可以由设计者根据基本结构设计自己所需要的物镜。在照相物镜的设计上,基本都要求的是大视场,所以设计时需要对像差的校正也多一些。 设计所要求的三片型照相物镜的相对孔径D/ f′= 1/4.5,根据光学特性的要求,物镜的视场角2ω=40°,物镜的焦距为f′=100mm。该次设计的三片型照相物镜是在一般的结构上进行优化设计的。 关键词:照相机,三片型照相物镜,像差,Zemax One kind of 3-piece type camera photographic lens design ABSTRACT The role of photographic lens is that take the outside world in the light-sensitive film on the imaging features to create scenes like the film exposure. 3-piece type camera photographic lens is the foundation of a lot of camera photographic lens at present. Many photographic lens development is based on the 3-piece type camera photographic lens. At the first, 3-piece type camera photographic lens is put the two same convex lens on a concave lens side. Make the Total light focal degrees is zero, Constitute a symmetric structures. To completely eliminate the field bending. But the present 3-piece type camera photographic lens by designer according to basic structure design which is needed. In the design of the camera photographic lens, all requests is basically the big field of view. So the design need more correction to the aberration. The design requests objective lens relative aperture D/ f′ = 1/4.5, according to the optical character request, objective lens angle of view 2ω=40°, and the focus of the photographic f′=100mm. In this design, the 3-piece type camera photographic lens is carries on the optimized design in the general structure.
