Sensor position accuracy
Housed standard and Flex cameras: Sensor
shift and rotation
The following table defines the manufacturing accuracy for sensor positioning with
housed standard and Flex cameras.
Sensor alignment for bare board cameras
The sensors in Alvium bare board cameras are not aligned to a lens mount. You
must align these cameras into housings individually, which can be difficult and
expensive. As a possible solution, Alvium Frame cameras provide alignment areas
and holes to fit into individual housings, see Alvium Frame - use your own optical
mount on page 19.
