Inserting a variable ND transmission filter at the aperture stop will modify the diffraction pattern of a lens. The reduced transmission at the center of the aperture will favor performances at high frequencies, while reducing transmission at the edge will favor low-frequency performance. Apodizing filters are used to eliminate intensity variations in optical systems. ISO 9001:2015 and ITAR.
