2.2.2 Inserting the eyepiece reticle
The eyepieces W-PL 10x/23 Br. foc. are intended
for use with eyepiece reticles.
The slight image shift caused by the additional
path through the glass is taken into account on
the diopter scale by the fact that the zero point
position is indicated not by the white dot (2-4/W)
but by the red dot (2-4/R).
The eyepiece reticles (2-4/1) have been adhered to
screw-in mounts (2-4/2) by the manufacturer to
allow easy replacement.
To replace an eyepiece reticle, remove screw-in
mount (2-4/2) with eyepiece reticle (2-4/1) and
replace it with a screw-in mount containing the
required eyepiece reticle.
☞
If eyepiece reticles are inserted into the unscrewed mount by the customer, attention must be
paid to the labelling being visible the right way up after insertion.
Compensation of ametropia when eyepiece reticles are used
For the correct use of an eyepiece reticle, two focusing eyepieces are required to allow the user to
compensate for differences in the visual performance of his two eyes.
• Use the focusing eyepiece to focus on the eyepiece reticle; focus on the edge of the field of view if no
eyepiece reticle is used.
• Use the focusing drive to focus on the microscope image of a specimen through the eyepiece set as
described above.
• Then use the second focusing eyepiece to focus the microscope image for the second eye. The
position of the focusing drive on the microscope stand must not be changed.
