适用范围:This part of ISO 14490 specifies the test methods for the determination of the following basic characteristics of telescopic systems and observational telescopic instruments:
— angular magnification (see Clause 4);
— entrance pupil diameter (see Clause 5);
— exit pupil diameter and eye relief (see Clause 6);
— angular field of view in the object space (see Clause 7);
— angular field of view in the image space (see Clause 8);
— angular field of view in the object space for spectacle wearers (see Clause 9);
