Continuously variable apodizing filters are used to eliminate intensity variations in optical systems. Inserting a variable transmission filter at the aperture stop will modify the diffraction pattern of a lens.

Two types: Clear Center, density distribution increases in a radial direction from the center to the edge, and Dark Center, density increases from the edge to the center of substrate.
