Bullseye® Apodizing ND Filters: Dark Center

Bullseye® Apodizing ND Filters: Dark Center

Bullseye® Apodizing filters: dark center are used to eliminate undesirable intensity variations in optical systems. The Gaussian density distribution increases in a radial direction from the outside edge to the center. Reynard Corporation has a line of stock Bullseye® Apodizing filters: dark center that meet general optical system requirements. These Bullseye® Apodizing filters: dark center are manufactured on high quality BK-7 substrate, are available with a density from 1 to 5 and a diameter of 25mm or 50mm.

Reynard Corporation also offers Custom Bullseye® Apodizing Filters: Dark Center which can be designed for any mathematical function regardless to the size of the beam.  These filters are produced on a custom basis to meet any distribution function, available on any substrate material and can be designed to operate at any wavelength from the UV to the Far Infared.

These filters are also supplied in an Bullseye® Apodizing Filter: Clear Center configuration. That is, the density increases from the center to the outside edge of the substrate.
