标准摘要
[中文适用范围]: ISO 14490的本部分规定了确定望远镜系统和观测望远镜仪器的以下基本特性的测试方法: ——角放大率(见第4章); ——入瞳直径(见第5条); ——出瞳直径和出瞳距离(见第6条); ——物体空间中的视场角(见第 7 条); ——图像空间中的视场角(见第8条); ——眼镜佩戴者在物空间中的视场角(见第 9 条); ——从目镜射出的光束的准直(见第10条); ——图像旋转(见第11条); ——最近观察距离(见第 12 条)。 [外文原描述]: ISO 14490-1:2005 specifies the test methods for the determination of the following basic characteristics of telescopic systems and observational telescopic instruments: angular magnification; entrance pupil diameter; exit pupil diameter and eye relief; angular field of view in the object space; angular field of view in the image space; angular field of view in the object space for spectacle wearers; collimation of the bundle of rays emergent from the eyepiece; image rotation; closest distance of observation.
