Neutraldichtefilter (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.

Features

• High accuracy
• Large clear aperture
• High damage threshold
• Broadband attenuation for DUV to IR wavelengths
• Well defined 1 or 2 dimensional transmission profiles
