Inserting the eyepiece reticle
Eyepiece reticles can be set into focusable
eyepieces.
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
(Fig. 16/
W
) but by the red dot (Fig. 16/
R
).
The eyepiece reticles (Fig. 16/
1
) are glued to screw-
in mounts (Fig. 16/
2
) for easy fitting and removal.
To replace an eyepiece reticle, simply unscrew the
screw-in mount (Fig. 16/
2
) with eyepiece reticle
1
) and insert the new screw-in mount with
the required eyepiece reticle.
If you wish to insert an eyepiece reticle into a mount, you should ensure that the labeling on
the eyepiece is still visible in the correct position after the eyepiece has been reinserted.
Adjusting for compensation of ametropia when using eyepiece reticles
Correct use of an eyepiece reticle requires two focusable eyepieces, so that the user can compensate for
differences in visual acuity between their two eyes.
•
Use the eyepiece focus control to bring the eyepiece reticle into focus. If no eyepiece reticle is used,
focus on the edge of the field of view.
•
Once the eyepiece has been adjusted, bring the image of the specimen into focus using the focus
drive.
•
Now adjust the second eyepiece to bring the microscope image into focus for the second eye. The
position of the focusing drive on the microscope stand should not be changed after this.
