The EP is in the system object space, and WebDec 4, 2016 · The entrance and exit pupils--which together are known as the pupil planes--are the planes in which the images of the system's aperture stop are located. The pupil function, however, is not an image of the aperture stop of the system; it's a 2D Fourier transform of a field. WebTo find the eyepiece exit pupil -the diameter of the beam of light coming out of the eyepiece - divide the eyepiece focal length by the telescope focal ratio. Thus, while a 10mm eyepiece has a 1mm exit pupil with an f/10 scope (10/10 = 1), the same eyepiece has a 2mm exit pupil with an f/5 scope (10/5 = 2).
