5.4 Position accuracy of the sensor

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

It cannot be guaranteed that the sensor cover glass or filter glass are absolutely parallel to each other.
C-mount/TFL-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.
