7.7 Magnification Changer

Optionally, a coded magnification changer can
be used, which is manually operated.
On the knurled ring, the following magnification
factors can be set:

B Stand

M Stand

1x

1x

1.25x

1.5x

Immersion objective (released)

For lockable immersion objectives:

• Lock these by pushing the front part upwards

until it stops (approx. 2 mm).

• Then, after a gentle turning motion to the right,

the objective is locked (Fig. 64).

For objectives with corrective mounts:

• Turn the knurl to adjust the objective to the

thickness of the cover glass.
