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.
The oblique lighting unit is located on the front part of the sub-gantry camera.
Fig. 5.5 - 2 Oblique lighting unit for the sub-gantry camera
Oblique lighting may be switched on instead of the existing lighting (see table in Section 5.5.2 on
page 160
).
PLEASE NOTE
Oblique lighting can only be used on the “sub-gantry camera”. 5
