Use Of Indicator Markers; Installing The Condenser; Centering The Condenser - Optika Italy M-1157 Serie Instruction Manual

5.3

Use of indicator markers

• Once the inserts are installed, use the magnetic
markers to quickly identify the position of each
single inserto.
1. Align the positioning number of the optical insert
installed in the condenser ② with the reference
number ① on the cover (Fig. 7) and then apply
the magnetic marker.
• When one of the eight available capacitor posi-
tions is inserted, a dot "¡" appears inside the cor-
responding window on the condenser cover. This
indicates that the optical insert installed in that
position is currently present in the optical path.

Centering the condenser

• Refer to the instruction manual of the microscope.
1. Place the specimen on the stage, insert 10x
objective into the light path and focus.
2. Insert the front lens of the swing-out condenser
①. (Fig. 9)
3. Rotate the field
counterclockwise direction, to fully close the
diaphragm.
4. Rotate the condenser height adjustment knob ③
to focus the edges of the diaphragm.
5. Rotate the two centering screws ④ to bring the
bright spot in the center of the field of view.
6. Gradually open the diaphragm. The condenser
is centered when the diaphragm image is
symmetrical to the field of view.(Fig. 10)
