5.5.4 Technical data
5.5.5 Optical centering with oblique lighting
5.5.5.1 General
For optical centering, the special features of the ceramic substrate must be taken into account.
The contrast depends very much on the paste used for the adjustment structure, the clear area
surrounding the adjustment structure, and the type of illumination. 5
The oblique lighting unit with ‘normal light’, ‘blue light’ and ‘IR light’ is located on the front part of
the sub-gantry camera.
