6.6 White balance
The Haag-Streit IM 900 is optimized for maximum image quality with the Haag-Streit
slit lamp BQ 900. The image quality is dependent, among other things, on the
correct calibration of the color tones to the respective slit lamp illumination. We
recommend performing a white balance in order to improve the image quality and
achieve a realistic color reproduction.
6.6.1 Slit lamp preparation
1. Turn the slit lamp on.
2. Filter position 'open' (no filter).
3. Select a 16 × magnification.
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
focusing.
7. The brightness of the slit lamp's illumination should be set in such a way that
the greycard's structure is clearly discernible.
6.6.2 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
WARNING!
To achieve an optimal result during the white balance, the image must
be homogeneously illuminated.
