4.3 Evaluation of a Flatfield
(1) Inspect the developed image for homogeneity:
Compare the prints of the flat field sample with your exposed flat field at
a light box.
· If there are no lines visible or the effects are less than on the example,
the image quality is all right.
· If there are unacceptable effects, compare with the following sketches.
Calibration lines
Blurred dark lines in slow scan
direction on the flat field (see
beside).
· Check the position of the laser
beam via the fiber optics. Expose
another flat field and compare it
again with the sample.
If there are still unacceptable
effects, you have to redo shading
calibration as described in section
6.6.
Expose another flat field and
compare it again with the sample.
If there are still
unacceptable effects, please
contact the Support Center.
