Each eyepiece should be set individually by turning the knurled ocular refraction
ring with dioptre scale until the projected slit can be seen in focus. The setting is
performedfromthe(+)tothe(-)sideatlowmagnification.
•
The sliding occluders (86) are used to set the correct working distance for the ex-
aminer from the eyepiece.
•
Examiners who do not wear glasses: Pull the occluders out as far as they will go.

5.3 White balance
The image quality is dependent on the correct calibration of the color tones to the
respective slit lamp illumination. We recommend performing a white balance in or-
der to improve the image quality and achieve a realistic color reproduction.
5.3.1 Slit lamp preparation
1. Turn on the slit lamp
2. Filterposition‹open›(nofilter)
3. Setmagnificationto16x
4. Completely open the slit diaphragm
5. Connect the diffuser upstream
6. Position the HAAG-STREIT greycard in front of the slit lamp and use it for fo-
cusing
7. The brightness of the slit lamp's illumination should be set in such a way that
the greycard's structure is clearly discernible.
5.3.2 Conducting a white balance
1. Start the ‹EyeSuite Imaging› software
2. Activate the intensity auto mode
3. Open the ‹White balance› application
4. Start the ‹White balance› by activating the ‹Calibration› function
