The required minimum height and width of the viewing slit depends on the following
parameters, among others:
•
Deviation from the ideal flatness of the scan field at the end of the viewing slit
•
Light spot size at the end of the viewing slit
•
Vibrations that affect the flatness of the scan field or the geometry of the viewing
slit
For a viewing slit with length a ≤ 200 mm, the viewing slit must be at least 28 mm high
(b, c ≥ 14 mm). The viewing slit must be wide enough to leave at least 16 mm of space
free next to each field.
If the viewing slit is longer (a > 200 mm), a case-by-case consideration is required.
