Reynard Corporation (San Clemente, CA) recently introduced the Bullseye® inverted apodizing neutral density filter. This filter is part of the Bullseye® Apodizer line of customizable gradient filters. These filters eliminate undesirable intensity variations in optical systems. The density of the filter increases radially from a clear center, where light is usually at its peak intensity, to the outside edge, where it can become completely opaque.

The Bullseye® apodizing filter can be designed for most distribution functions, such as a Gaussian function, regardless of the size of the beam. The distribution function, substrate type, and bandwidth are a function of the customer’s specific requirements. Inserting a Bullseye® apodizing filter at the aperture stop of your imaging system modifies the intensity variations of your light source, which can result in the elimination of edge diffraction patterns.
