Apodization Filters

A Typical Special Engineering Projects of the Past.

Apodization is an optical filtering technique, and its literal translation is "removing the foot". It is the technical term for changing the shape of a mathematical function, an electrical signal, an optical transmission or a mechanical structure. In optics, it is primarily used to remove Airy disks caused by diffraction around an intensity peak, improving the focus.

HTA Photomask has experience making binary optical components for apodizing light to gray scale levels.
