Theia Technologies' individually calibrated lenses provide lens-specific optical performance data to enhance image processing and improve image quality. The calibrated lenses with motorized zoom and focus simplify camera setup in applications that have variable camera positions and object distances, enhancing object resolution in dynamic environments and applications such as mobile robots, ITS, ANPR and other industrial imaging applications.

Calibrated lens back focal length (BFL) calibration procedure
Due to the tolerances in the camera sensor and mount positions, there is a difference between the lens best focus position and the calibrated focus position. To mitigate this, the lens focus position should be set visually and compared to the calibrated focus motor step from the data file at several focal lengths. The Back Focal Length (BFL) calibration procedure is described in application note AN004. Depending on the application, a fine focus adjustment may be required for optimal focus.
