ISO 14490-1:20 05规定了测定望远镜系统和观测望远镜仪器下列基本特性的试验方法:
角度放大;入瞳直径;出瞳直径和眼睛浮雕;所述对象空间中的角视场;图像空间中的角视场;用于眼镜佩戴者的物体空间中的角视场;从目镜射出的射线束的准直;图像旋转;观察的最近距离。
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;
