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.

For ease of evaluating Theia’s motorized lenses Theia offers a motor control board. This board allows the user to control zoom, focus, P-iris, and IR cut filters (there is no control for DC auto iris lenses). For evaluation, we offer a Windows based test program to communicate over USB. You may also communicate over i2c or UART from within your own program. Details are covered in the instruction manual from the link below, as well as CAD model and drawing of the board.
