Start the Flat Field calibration tool via the CamExpert menu bar:
Pre-processing • Flat Field Correction • Calibration.
Flat Field Calibration Window
The Flat Field calibration window provides a three step process to acquire two reference images and then save the
flat field correction data for the Genie used. To aid in determining if the reference images are valid, a histogram tool
is provided so that the user can review the images used for the correction data.

Click on the Advanced Setting button to change the default number of frames averaged for each calibration
step. The default value is 10 frames.

Setup the camera to capture a uniform black image. Black paper with no illumination and the camera lens' iris
closed to minimum can provide such a black image. Or cover the lens with a black lens cap.
