Product Family Description

  • Bull’s Eye Filter Type Decreases Radially from Center
  • Reverse Bull’s Eye Type Increases Radially from Center
  • Ideal for Eliminating Intensity Variations in Optical Systems

Apodizing filters are used to create an even illumination profile in an optical system. Bull’s Eye type filters feature a high optical density in the center which decreases continuously to an uncoated edge, and are commonly used to flatten the intensity profile of Gaussian beams. The Reverse Bull’s Eye type features a high optical density coating on the filter’s edge which decreases continuously to an uncoated center.

Our standard filters are available in 25 and 50mm diameters, with end densities of 1.0 and 2.0. For different substrates, sizes, or intensity profiles, please contact our Applications Engineering Department.
