Calculating the Total Magnification and Field of View Diameter
Parameter
MO
Magnification of the objective
ME
Magnification of the eyepiece
z
Magnification of the changer position
q
Tube factor, e.g. 1.5× for coaxial incident light, 1.6× for 45°
ErgoTube
r
Factor 1.25x if the planachromatic and planapochromatic
objectives of the MZ125/MZ16 are used on the MS5, MZ6,
MZ75 or MZ95
NFOV Field number of the eyepiece. Field numbers are printed on the
eyepieces: 10× = 21, 16× = 14, 25× = 9.5, 40× = 6.
Example
MO
1× objective
ME
25×/9.5 eyepiece
z
Zoom position 4
q
Coaxial reflected light 1.5×, tube factor
r
Factor 1.25×
Calculation example: Magnification in the binocular tube:
MTOT VIS = MO × ME × z × q × r
or
1 × 25 × 4 × 1.5 × 1.25 = 187.5×
