Compensating Defective Vision at
the Eyepieces and Inserting the
Eyepiece Pointer or Eyepiece
Micrometer
The eyepieces (Fig. 32/
3
) can be equipped with
fold-over rubber eyecups (Fig. 32/
1
: pulled out;
2
: folded over). Die eyecups are supplied
together with the eyepieces, but are not yet
mounted.
Both eyepieces are suitable for spectacle wearers.
They contain additionally a focusing ring for the
compensation of defective vision. The provided
diopter scale serves to facilitate finding the correct
setting.
If required, an eyepiece pointer or an eyepiece
micrometer with a diameter of 23 mm can be
inserted in one eyepiece.
To this end, follow this procedure:
•
Unscrew the stop (Fig. 32/
5
) by hand from the
eyepiece.
•
Insert the eyepiece pointer (Fig. 32/
4a
) or the
eyepiece micrometer (Fig. 32/
4b
) into the
eyepiece (with the coated side facing your eyes).
•
Screw in the stop again.
•
Insert the eyepiece into the tube.
•
Attach the eyecups.
•
Turn the focusing ring of the eyepiece (Fig. 32/
3
) to focus on the wedge-shaped figure of the eyepiece
pointer.
•
Put the specimen onto the specimen stage. Look at the specimen through the eyepiece with the
eyepiece pointer and bring the microscopic image into focus using the focusing drive.
•
When in the above-mentioned eyepiece both the microscopic image and the eyepiece pointer appear
sharply defined, focus the image for the second eye by turning the focusing ring of the second eyepiece.
Having done so, both microscopic images inclusive of the eyepiece pointer are focused.
From now on, you should focus onto the specimen using the focusing drive only.
