| Calculating
Magnification
M = magnification of
optical system
ft =
focal length of the binocular tube
fo =
focal length of objective lens
Me =
magnifying power of eye piece
A =
magnification coefficient on body of scope
Example:
Binoculars (ft)-
f=170
Working distance (fo)-
f=175
Eye pieces (Me)-
10X
Mag. Coefficient (A)- 1.6
M = 170
/ 175 x
10 x
1.6
M=15.54X
