ZEISS SL Imaging Solution Quick Guide
Option 1: Eyepiece with crosshair (recommended)
This method applies to all types of slit lamps
1.
Insert the eyepiece with crosshair into the right side of the
binocular tube (this is where the camera is located).
2.
Close the left eye and turn the diopter ring of the eyepiece
until the crosshair appears sharp. Start from maximum "+"
to avoid accommodation.
3.
Ensure the crosshair and observed object are both in focus.
4.
Check the monitor image; it should now be in focus.

How to align the slit lamp and camera correctly
Option 2: Monitor focus (no crosshair eyepiece
or focus rod)
This method applies to all types of slit lamps
1.
Attach an object (e.g., a business card) to the headrest.
2.
Focus on that object using the highest magnification while
looking only at the monitor.
3.
Block the slit lamp by activating the quick action break.
4.
Looking through the microscope, without moving the slit
lamp, adjust your eyepieces (monocular).
Tips:
• Keep in mind which beam path is recorded to avoid
shadows and reflexes
• Use the aperture to increase the depth of field
• Use the optimal type of illumination
• Big illumination angle for 3D information
• For people who wear glasses, it is necessary to slide
in eyecups
• Reduce ambient light for better results
• Accommodation is more pronounced among younger
people (that’s why adjusting correctly, and Option 1,
is important)
