3.4.1
Inserting the eyepiece reticle
Eyepiece reticles (3-5/
3
) may be inserted into eyepieces marked with a red dot.
The slight image shift caused by the additional path through glass is taken into account on the diopter
scale by the fact that the zero point position is indicated not by the white dot, but the red dot.
Make sure the line figure always faces the field stop.
Eyepiece reticles may only be installed by Zeiss service technicians working in a dust-free
environment.
3.4.2
Compensation of ametropia when eyepiece reticles are used
Correct use of an eyepiece reticle requires two focusing eyepieces, e.g. PL 10x/23 Br. foc, to enable the
user to compensate for differences in the visual acuity of his or her eyes.
•
Use the focusing lens of the adjustable eyepiece to focus on the line figure of the eyepiece reticle.
•
Viewing through the eyepiece, use the focusing drive to focus on the microscope image of a specimen
placed on the stage.
•
As soon as the microscope image and the eyepiece reticle are focused in the above eyepiece, turn the
focusing eye lens of the second eyepiece to focus the microscope image for the second eye.
On having done this, both microscopic images and that of the eyepiece reticle are focused.
From this point in time on, you should focus only with the focusing drive.
3.4.3
Inserting the fold-over eyecups
The eyepieces have a rubber eyeglass protection
ring to prevent scratches on spectacles. The
protection rings can be replaced with fold-over
eyecups when required.
•
Remove the eyeglass protection rings (3-5/
2
)
from the eyepieces and attach the eyecups
(3-5/
1
).
Sometimes the eyeglass protection rings are seated
very tightly in the eyepiece groove, so you may
need a blunt object (stick) to prod them off.
