• The slit image can be set vertically, horizontally or as diagonal as required by

turning the illumination facility on the handle (15) (locking points at 45°, 90° and

135°; stops at 0° and 180°; scale in 5° increments).

• To ensure that unimpeded binocular fundus examination is also possible at

lateral angles of between 3° and 10°, a short mirror is used, the illumination

turned 90° using the locking screw (15) and tilted in 5° steps using the latch

(23), and the illumination and microscope turned to the central position (0°).

• Front lenses and contact lenses are used to examine the ocular fundus.

Diffuse illumination:

• Connecting the diffusor (13) upstream creates diffused illumination. This allows

monitoring of the overview and can be used to capture the overview.

Indirect illumination:

• For observation in regredient light (indirect illumination), the centring screw (22)

is loosened in order to move the slit image out of the centre of the visual field.

Tightening the screw centres the slit image again.

Slit tilting:

• The latch (23) can be used to tilt the illumination in 5° steps. This creates an

angled light beam during horizontal slit orientation. Tilting the slit enables reflex-

free examination with contact lenses (fundus and gonioscopy) and magnifying

lenses.

6.4 Background illumination (flash)

When the flash is triggered, the light is

transferred to the background illumination by a

light guide.

6.5 Photo diaphragm pre-selection

85. Rotating knob for diaphragm pre-selection

You may select between levels 1 through 5,

each with an increasingly smaller aperture. The

size of the interval is equivalent to one f-stop.

Level 1 = largest aperture

(smallest depth of field)

Level 5 = smallest aperture

(largest depth of field)

86. Rotating knob for diaphragm actuation

Turning one of the two knobs on the right and left allows you to close the

diaphragms to the preset aperture during observation in order to get a preview of the

expected depth of field.

b. Grey filter (10%)

c. Red removal filter

d. Reserve opening for filter of choice ø 15 mm (0 / –0.2), thickness 2.5 mm

e. Fixation star (predominantly used for fixation examination of cross-eyed

children with amblyopia)

f. Apertures of ø 8, 5, 3, 2, 1 and 0.2 mm

g. Display of slit length adjustment from 1 to 8 mm
