Determining dioptres for users
The individual dioptres can be regulated continuously from +5
to –5.
The treatment microscope ensures a high degree of fatigue
resistance when the dioptre setting is correct for both eyes.
Preparations
➩Open any double-iris diaphragm used.
➩Turn both eyepieces to <0>.
Sharpening test object image:
➩Select magnification 13.7.
➩Place a flat test object with sharp contours under the
eyepiece at the working distance.
➩Move the microscope toward the test object via the camera
or graticule until it appears sharp.
Setting dioptre
➩Select the lowest magnification (magnification 6.4).
➩Without looking into the eyepieces, turn both eye lenses
to +5.
➩Slowly turn the eyelenses toward –5 individually for each eye
until the test object appears sharp.
Checking the setting
➩Select the greatest magnification (magnification 13.7).
➩Check sharpness and adjust if necessary.
Setting up eyepieces
Setting dioptre values for users
The dioptrics are to be set exactly separately for both eyes;
only then does the sharpness remain constant within the entire
zoom range = parfocal.
➩Read dioptre values of the operating doctor at the control unit
(see Page 20).
➩Set dioptre values at each eyepiece individually with the
setting ring (2).
Setting eye-base and pupil-base
➩Set eye-base with setting wheel (3).
➩Set pupil-base with rotating ring (1).
Attaching protective glass to eyepiece
➩Place the protective glass, which can be sterilised with gas,
on the eyepiece so that the markings on the optics carrier (4)
and on the protective glass (5) are aligned.
➩Lead protective glass into the bayonet lock upward in
direction (a).
➩Turn protective glass in direction (b) until it engages.
