Calculating the Total Magnification and Field of View Diameter

Parameter

MO	Magnification of objective

ME	Magnification of eyepiece

z	Magnification changer position

qTube factor, e.g. 1.5× for coaxial incident light, 1.6× for 45° ErgoTube™

rFactor 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 binocular tube		Calculation example: field of view diameter in the specimen

MTOT VIS = MO × ME × z × q × r		NFOV
or		NFOV
or		∅ OF:
1 × 25 × 4 × 1.5 × 1.25 = 187.5×		MO × z ×q ×r
1 × 25 × 4 × 1.5 × 1.25 = 187.5×
