Bullseye® Apodizing ND Filters: Clear Center

Bullseye® Apodizing ND Filters: Clear Center

Bullseye® Apodizing filters: clear center are used to eliminate undesirable intensity variations in optical systems. The Gaussian density distribution increases in a radial direction from the center to edge. Reynard Corporation has a line of Bullseye® Apodizing filters: clear center that meet general optical system requirements. These Bullseye® Apodizing filters: clear 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.

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

Reynard Corporation also offers Custom Bullseye® Apodizing Filters: Clear Center which can be designed for any mathematical function regardless of 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 Infrared.  Click here for a custom quote.
