Use of additional lens (SZB260/SZT260)
Screw the desired additional lens on the microscope
body. (Fig. 14)
Each additional lens has a specific Working Distance
(see table below).
The stroke of the focus adapter could not compen-
sate the different working distances of the several
additonal lenses.

9.6.1 Use of 0.5X additional lens
0.5X additional lens has a Working Distance of 165
mm and therefore the total stroke of the focus pillar
cannot compensate.
In order to let the 0.5X additional lens working pro-
perly, proceed as follows:
1. Screw the additional lens on the microscope body
as already described in chapter 8.6.
2. Uninstall the microscope body from the head hol-
der.
3. Install the provided spacer
①
in the head holder
and screw the fixing knob
②.
(Fig. 15)
4. Re-install the microscope body onto the spacer
and screw the fixing knob
③.
(Fig. 16)
5. Begin working normally.
