system cable (video cable) from the OPMI®
microscope.
2) Remove four screws (1) and cover (2).
Fig. 1: Remove cover
3) Unscrew four screws (3) and remove OPMI®
pico illumination module (4).
Installation:
1) Insert OPMI® pico illumination module (4) and
mount it by tightening four screws (3) only
slightly.

5.2 Exchanging a filter
1) Swing out the filter to be exchanged (5) by
turning filter selection ring (6).
2) Remove filter (5) from the mount and insert the
new filter.

Adjustment:
1) Switch the magnification changer to its free-
passage position (position 1).
2) Align OPMI® with the test object (alignment
template enclosed) and focus the microscope
on it.
3) Move and tilt the illumination module in such a
way that the illuminated field is radially
centered to within ± 1 mm relative to the outer
reference circle.
Fig. 4: Focus the microscope
4) Tighten screws (1) and secure them in position
by applying blue threadlocker to their heads.
5) If the edge of the illumination field is out of
focus, loosen the set screw (2) and shift the
light guide sleeve (3) to obtain correct focus.
6) Tighten set screw (2)
7) Re-attach cover (2 Fig. 1).
Note
In case of a not adjustable offset in vertical
direction, shims must be inserted between
illumination unit and OPMI body at the two
upper or lower screws (1) depend on the
offset direction (see drawing OPMI® pico
Basis –1095-102).
Fig. 5: Secure the microscope in position
Note
There are two versions of illumination units existing.
One version (no. 1053-917) without UV safety filter for OPMI® pico and the
other version (no. 1153-460) with UV safety filter for OPMI® pico i (ophthalmic version).
For easy differentiation between the two versions, the front surface of the light guide sleeve
is anodized black for the unit without safety filter and
anodized to natural aluminium for the unit with safety filter
When installing an illumination unit in an OPMI® pico i, make sure, to use the version
1153-460 (with safety filter) as otherwise damage to the patient`s eye is possible.

pins in their boreholes and loosen the shafts by
turning them counterclockwise).
6) If one of the shafts remains fixed, unscrew the
objective lens and switch the magnification
changer to its free-passage position. Secure the
changer in this position using a piece of round
wood or a similar device and remove the shaft.
Fig. 7: Remove the camera module

3) Lubricate the front surfaces of the changer with
GF 50 grease.
4) Re-install the changer drum in laterally correct
position.
Fig. 8: Remove changer drum
5) Lubricate the running surfaces of shafts (9) with GF 50 grease. Screw them back in and tighten

Adjustment:
Note
The following description assumes that the optics in the changer has been correctly
adjusted, i.e. no image shift or binocular error occurs when the changer is switched from
one magnification step to another as well as no focus differences.
Tolerances:
Binocular alignment:
Convergent deviation ≤ 15´
Divergent deviation ≤ 5´
Hight deviation ≤ ± 5´
Focus alignment:
Difference of focal planes left / right
≤ ± 0.25 mm at γ= 2.5
≤ ± 2 mm at γ= 0.4
Fig. 9: Alignment template
7) If provided, insert an eyepiece including a reticle
in the port on the right-hand side of the tube.
8) Switch the magnification changer to the free-
passage position (position 1) and align and
focus OPMI® on the test object (alignment
template enclosed).
9) Switch to magnification step 2.5.
10) If an image jump occurs in the vertical direction
of ≥ ± 0.5 mm, loosen screw (1) and move
catch spring (2) using a scriber or a similar
device in such a way that no image jump
≥ ± 0.5 mm occurs any longer when the
changer is switched from position 1 to
position 2.5.

7.1 Opening the illumination unit
Opening:
1) Remove the lamp slide-in module.
2) Disconnect the light guide.
3) Remove the camera control unit, if necessary.
4) Remove four Phillips screws (1) and two hex
socket head screws (2).

power switch slightly inward and make sure you
do not damage or lose the release button for
the lamp module when removing the other half
of the housing.
Mounting:
1) Insert the release button for the lamp module in
the housing and re-attach the halves of the
housing, making sure that the release button is
correctly positioned.
Fig. 35: Remove the lamp slide-in module
2) Align the halves of the housing with each other and screw them together using screws (1 + 2).
3) Insert the lamp module and check that it is smoothly ejected. If necessary, loosen the halves of the
housing and re-align them.
4) If provided, re-install the camera control unit.
5) Connect the light guide.
7.2 Checking and adjusting the maximum lamp voltage
1) Turn the brightness potentiometer on the
suspension arm ccw as far as it will go.
2) Move the suspension arm downward until the
inclination switch is activated.
3) Set the measuring range of the True-RMS
voltmeter to 20 or 25V AC.
4) Connect the voltmeter to X17 and X18
terminals (3 + 4).
5) Switch on the power switch.
6) Turn the brightness potentiometer slowly cw as
far as it will go. The maximum lamp voltage
must be 12.4 +0V / –0.3V under load with the
halogen lamp.
7) If the voltage deviates from this value, use R 13
potentiometer (5) to adjust the voltage
to 12.4 –0.1V.
Fig. 36: Check, adjust the lamp voltage
Caution
Do not exceed 12.5 V during the adjusting procedure.
8) Re-install the dummy cover or camera control unit (4 Fig. 26).
