11.5.4 Technical data
11.5.5 Optical centering with oblique lighting
11.5.5.1 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. 11
The oblique lighting unit is located on the front part of the sub-gantry camera. 11
