Neutral Density Filter
Our neutral density filters allow broadbandattenuation for a spectral range from VIS to NIR. Due to their excellentsurface quality the absorptive and reflective filters enable precise beamattenuation for low power applications. The level of attenuation is specifiedby the optical density. Filters with different optical densities can be combined.A filter adapter is available to mount the filters on the STCam aperture.
