Bullseye® Apodizing Filters:

Bullseye® Apodizing filters are custom density gradient filters that change radially from the center to the outside of the optical component. These filters are used to eliminate undesirable intensity variations in optical systems or to modify the wavefront of an optical source.

Two types:
1. Dark Center: The normal Bullseye® Apodizing configuration decreases in density radially from a dark center, where light is usually at its peak intensity, to the outside edge, where it can become completely transparent. Normal apodizing filters are used to modify a Gaussian light source into a ‘top-hat’ type of output with a flat wavefront.

2. Clear Center: In the Bullseye® Inverse Apodizing configuration, the density increases from the center to the outside edge. Following a Gaussian distribution from a clear center, the outer edges of the optic will achieve a density of OD1 to OD5, depending on the product selected.
