cornea. This initial setting is verified with the naked eye. Fine tuning is
performed by tilting the control lever while observing via the stereo microscope
(21).
• The slit width is set left or right with the rotating knob (28), as is the angle
between the stereo microscope and illumination.
• The slit image can be set vertically, horizontally or diagonally as required by
turning the illumination facility on the handle (5) (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 (8) is used, the illumination
turned 90° using the setting screw (5) and tilted in 5° steps using the latch (27),
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 (9) upstream creates diffused illumination. This allows
monitoring of the overview and can be used to capture the overview with an imaging
module.
Indirect illumination:
For observation in regredient light (indirect illumination), the centring screw (25) 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 (27) 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.
