Adjust the white balance for more natural looking images
Camera settings
Without white balance adjustment With white balance adjustment
How to get quality images using the software
Override the default white balance by following the steps below:
• Hold a white sheet of paper in front of the slit lamp
• Swivel in the diuser for a homogeneous illumination
• Reduce illumination to a minimum (the test paper should appear grey on the screen)
• Make sure there is no glare
• Click the White balance button (each prole requires a separate white balance)
Image quality – Best: lower resolution, but higher frame rate
Automatic adaption of gain and exposure time – Increase illumination
on SL (may cause noise)
Exposure time – Dependent upon the movement of patient and SL; low
exposure time for videos and moving patients
Gain – Electronic amplication of the signal. The darker the output signal,
the higher the basic noise. Keep Gain as low as possible. Instead, increase
illumination at the SL.
Gamma – Changes black/white appearance without changing color
temperature (keep at 100%)
Fine setting – Color information; 100% = maximum color information,
0% = black/white image
Coarse setting saturation – Leave at 0% for the most natural impression.
Higher value will amplify the given color information.

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 magnication 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 reexes
• Use the aperture to increase the depth of eld
• 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)
