Optics and optical instruments. Test methods for telescopic systems -- Test methods for basic characteristics
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);
collimation of the bundle of rays emergent from the eyepiece (see Clause 10);
image rotation (see Clause 11);
closest distance of observation (see Clause 12).
