摘要

本文所论述的f=20mm、D/f=1/1.19、2ω=68.5°

35mm电影摄影物镜

是目前我国大孔径、大视场定焦距系列中焦距最短的一个.下面就二个方面问题做介绍

1.设计过程简介.2.设计结果.

Abstract

This paper describes a photographic lens(f=20mm

D/f=1/1.19

2ω=68.5°)for 35mm motion picture camera. Its focal length is the shortest with large-aperture and large field of view in a series of photograph lenses with fixed focal length for 35mm motion picture camera in our country. In the following

we shall describe both the process of design and an example of the design.
