9.8 Use of additional lenses 0.3X-0.5X
The additional lenses 0.3X and 0.5X have a long working dis -
tance and therefore the total stroke of the focusing column can -
not compensate.
To make the additional lenses 0.3X and 0.5X work correctly, pro -
ceed as follows:
1. Screw the additional lens on the microscope body as already
described in chapter 9.7.
2. Uninstall the microscope body from the head holder.
3. Install the spacer
①
in the head holder and screw the fixing
knob
②.
(Fig. 50)
4. Re-install the microscope body onto the spacer and screw
the fixing knob
③.
(Fig. 51)
5. Begin working normally.
9.9 Black/white stage plate (SZ-ST1 / 2 / 3 / 7 / 8)
You can use a black/white contrast disc to increase the contrast
of the image when working in incident light. (Fig. 52).
If you are looking at bright samples, place the disc with the black
side facing up.
