Specifications
Housed Alvium Frame: Sensor shift and
rotation
The following table defines the manufacturing accuracy for sensor positioning with
housed Alvium Frame cameras. For sensor tilt, see Housed Alvium USB cameras:
Sensor tilt on page 233.
Housed Alvium USB cameras: Sensor tilt
The following table defines sensor tilt as the variance between highest and lowest
pixel of a sensor along the z-axis, measured in micrometers for housed Alvium USB
cameras.
Values for Alvium Frame cameras
For sensor shift and rotation with Alvium Frame cameras, see Housed Alvium
Frame: Sensor shift and rotation on page 233. For sensor tilt, see Housed Alvium
USB cameras: Sensor tilt on page 233.
