9. Understanding Exit Pupil
Exit pupil is an important optical specification.
The approximate formula is:
Exit Pupil = Objective Diameter ÷ Magnification
For example:
A 40mm objective at 8×:
40 ÷ 8 = 5mm
A 50mm objective at 10×:
50 ÷ 10 = 5mm
This demonstrates why objective diameter and magnification should be considered together.
10. Field of View
Field of View, or FOV, represents the visible area through the scope.
Generally:
Lower Magnification → Wider FOV
