本文认为高斯光学是变焦距物镜的基础。当然对于变焦距物镜的小型化更应重视这个基础。在设计变焦距物镜时对其必须加深理解,选好初始参数,否则影响将是根本的。一般的军用望远系统变焦距物镜的特点是:小视场、低倍率、长焦距。例如,1.5~x变焦距指挥镜,其变焦比只有1.5~x,视场角为7°,但长位置焦距为358.14mm。所以,要使1.5~x变焦距物镜结构尺寸小型化并非是一件容易的事情。
This paper argues that Gaussian optics is the basis of a zoom objective. Of course, the miniaturization of zoom objective should pay more attention to this foundation. In the design of variable focal length lens must deepen their understanding, select the initial parameters, otherwise the impact will be fundamental. General military telescopic zoom lens system is characterized by: small field of view, low magnification, long focal length. For example, 1.5 ~ x zoom command mirror, the zoom ratio of only 1.5 ~ x, field of view of 7 °, but the long position of 358.14mm focal length. Therefore, to make 1.5 ~ x zoom lens structure size is not an easy thing to do.
