The neutral density filters allow broadband attenuation for a spectral range from VIS to NIR. Due to their excellent surface quality the reflective and absorptive filters enable precise beam attenuation for low power applications.
The level of attenuation is specified by the optical density. Filters with different optical densities can be combined. A filter adapter is available to mount the filters on the CinCam aperture (only for CinCam CCD/InGaAs).
