Features
Compact Variable ND Filter Hubs
The FR-CV-75 provides rotational adjustment for any of the 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 is compatible with the Circular Variable Metallic Neutral Density Filters having a 1 inch inner diameter. It 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.
Mounts with Pitch & Yaw Adjustments
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 used in 946, for adjustment. They're compatible with variable neutral density filters with 1 inch inner aperture. An integrated pointer on the mounts indicates the setting of the graduated scale on the attenuator.
