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)
