7.2 Position accuracy of the sensor
The following illustrations show the tolerance margins of the sensor position relative to the outer camera
housing. A maximum error in all directions (rotation, translation) cannot occur at the same time.

sensor (2)
It cannot be guaranteed that the sensor cover glass or filter glass are absolutely parallel to each other.
C-mount lenses can also be subject to inaccuracies of the flange back distance. The
tolerance usually is ±0.05 mm. In some cases, however, the inaccuracies of camera and lens
might add up, resulting in a total error > 0.05 mm.
Position accuracy, in each direction
±0.3 mm
Horizontal/vertical rotation (α)
±1.0°
Translational rotation (β)
±1.0°
Flange back distance
