10.1.1.3.3 Positioning accuracy of the sensor chip
The tolerance for positioning the sensors image area to the camera housing in all kind of direction is
shown in the figures below.
Since the translational and rotational positioning tolerances depend on each other, the worst case of
maximum rotational, horizontal and vertical misplacement cannot occur at the same time.

10.1.1.3.4 Maximum Immersion Depth for Lenses
Some C-mount lenses reach deep into the camera flange. This may cause the lens to push against
the back of the filter glass inside the camera or even make it impossible to screw in the lens.
The table below indicates the maximum possible immersion depth for each DCx model. The actual
immersion depth of a lens is given in the relevant data sheet. As lens parts with a small diameter are
allowed to reach deeper into the camera flange, the immersion depths are specified based on the
diameter.
