Positioning Accuracy Of The Sensor Chip; Maximum Lens Thread Length On A101Fc - Basler A101f User Manual

Mechanical Considerations

5.4 Positioning Accuracy of the Sensor Chip

On the A101 , the tolerance for the positioning of the sensor's image area to the camera housing
f
is ± 0.3 mm in the horizontal and vertical directions. Rotational positioning accuracy is as shown
in Figure 5-4. Reference position is the center of the camera housing.
Since the translational and rotational positioning tolerances depend on each other, the worst case
of maximum rotational and horizontal/vertical mis-positioning cannot occur at the same time.

5.5 Maximum Lens Thread Length on A101
!
As shown in Figure 5.5, when a C-mount lens is
used on an A101
must be less than 7.5 mm. A101
equipped with a C-mount lens adapter have an
internal IR cut filter. If a lens with a longer thread
length is used, the IR cut filter will be damaged or
destroyed and the camera will no longer operate.
Cameras equipped with F-mount lens adapters do
not have an internal IR cut filter.
