The reading distance of the scanner with the OM2000N is shifted by 10 mm towards the
scanner because of the internal optical path between the scanner and the OM2000N 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 OM2000N and the reflection on
the mirror surface. The combination of these effects produces the reading diagram
represented below:

The reading distance also depends on the amplitude of aperture used. In particular, wider
apertures require the scanner to be closer to the code in order to read at the extreme edges
of the sweep (see Figure 32 below).
