Neutral Density Filters

Digital neutral density filters are used to control the intensity profiles in illuminations and projection systems. These filters contain well-defined metal absorber micro-structures that are randomly distributed on a fused silica substrate. The density and size of the structures can be customized to meet precisely the transmission profile required by the application.
