C-Mount Absorptive Neutral Density (ND) Filters are pre-mounted in C-Mount housings to simplify their integration into optical systems. Each housing is engraved with the stock number as well as the optical density of the filter for easy identification. ND filters with optical densities ranging from 0.1 to 2.5 are available. C-Mount Absorptive Neutral Density (ND) Filters are ideal for exposure control in imaging applications and in light control applications for measuring instruments. Please contact us if your application requires a custom C-Mount Absorptive Neutral Density (ND) Filter with one of our standard Absorptive ND Filters.
