ND Filter Rotator, Compact, 7.5 mm Hub, 8-32 and M4

The FR-CV-75 provides rotational adjustment for any of Newport’s Circular Linear Variable ND Filters having a Ø7.5 mm inner diameter. The slim design minimizes blockage of the filter's clear aperture and, with its clamping thumbscrew design, it can accommodate filter thicknesses from 2 to 13 mm. This mount is unique in that it has both English (8-32) and metric (M4) post mounting threads clearly marked on its base. To prevent inadvertent rotation after adjustment, the FR-CV-75 incorporates a side-located locking screw.
