Changing the magnification (zoom)

All M series microscopes have an integrated zoom. The name indicates the zoom range covered:

★★	Leica M125 = 16.5:1
★★	Leica M165 C = 16.5:1
★★	Leica M205 C = 20.5:1

The rotary knob for the zoom can be used either left or right-handed.

Zooming

1.Look into the eyepieces.

2.Focus on the specimen.

3.Rotate the magnification changer until the desired magnification is configured.
