Abstract:
Scanning device for point-by-point photoelectric measuring of a transparent object, the device comprising:a transport arrangement for transporting the transparent object along a transport path through a scanning zone;a guide arrangement for guiding and positioning the transparent object in the scanning zone;an illuminating arrangement for exposing the transparent object located in the scanning zone with measuring light;and a photoelectric converter arrangement for converting the measuring light transmitted by the transparent object into corresponding electric signals and having optical means for directing the measuring light transmitted by the transparent object to the photoelectric converter arrangement, wherein;the guide arrangement includes a selectively adjustable moveable platform which is adapted for guiding and positioning of said transparent object, said transparent object being any one of at least two different formats; andthe moveable platform comprises at least two parallel guide elements adapted for said at least two different formats, said guide elements being selectively moveable into the transport path of the transparent object, the optical means including at least two projecting optics each associated with one of the guide elements.
