This article describes a technique employed in the development of anti-vignetting filters to be incorporated in wide angle lens systems. The technique requires no knowledge of the optical prescription, but would include lens parameters such as entrance pupil location, type of vignetting and intensity distribution across the image plane. Results are given for the application of this technique to an 85 degree camera objective.
