If the exit pupil of the instrument is larger than your entrance pupil, you waste light
. V. To calculate the exit pupil of a binocular, divide the objective size by the
magnification. For example, a 7X50 binocular delivers an exit pupil of 50/7=7.

Exit Pupil The exit pupil (or Ramsden disk) of an (pupil forming) HMD is the area
in space where all the light rays pass; however, it often is pictured as a two-
dimensional hole. To obtain the full FOV, the viewing eye must be located at (
within) ...

M = diameter of entrance pupil (objective) (17.16) diameter of exit pupil These
equations provide a very useful means for measuring the angular magnification
of telescopes, indirectly from the diameters of the entrance and exit pupils.
