Overview
Available calibration data
The following calibration data frames are provided in a JSON format data file. The calibration curves are monitored from lens lot to lot to verify the continued accuracy of the curves. When a Theia IQ lens™ is purchased, the most recent average data file is provided (available from online download).

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  Operating Note 004: BFL Compensation. Depending on the application, a fine focus adjustment may be required for optimal focus.
