Figure 5.1
Visual angle for oscillating mirror models
Otherwise, the scanner can be installed with a tilt angle of 17.5° in order to achieve a
horizontally symmetric deflection range.
Figure 5.2
Reading position of the oscillating mirror
In the above example, the zone in which the scanning lines meet the reflecting surface
vertically corresponds to a neutral area in the middle of the reading field.
The mirror can be deflected by up to 40°. In relation to the central axle of the exit
window, the deflection angle is asymmetric.
