7. Operation

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.

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

1.6x

2x

The selected factor is indicated in the display and included in the total magnification.
