Model FR-CV-75 (Filter, Optical Post and Post Holder Sold Separtely)
The FR-CV-75 provides rotational adjustment for any of Newport’s Circular Linear Variable ND Filters having a 7.5 mm inner diameter. It has both 8-32 and M4 mounting threads and a rotation lock. The 941 offers the widest possible aperture and provides basic mounting compatibility with posts, platforms and clamps. The spindle is integrated into a block with an array of tapped and clearance holes.
Models 946 and 946-M are precision kinematic mounts that provides angular adjustment of ±4° about each of two orthogonal axes to control the direction of the reflected beam from the face of the filter. The 946-M utilizes micrometers, instead of thumbscrews, for adjustment. An integrated pointer on the mounts indicates the setting of the graduated scale on the attenuator.
