The internal optical path from the scanner reading window to the GFC-200 window is
51 mm.
The reading distance of the DS2400N scanner with the GFC-200 is shifted by 51 mm
towards the scanner because of the internal optical path between the scanner and the GFC-
200 output window.
The reading performance also decreases in typical conditions by about 10% due to the
optical signal passing through the output window of the GFC-200 and the reflection on the
mirror surface.
The combination of these effects produces the reading diagram represented below:
