Model 946 is a precision kinematic mount for circular variable neutral density filters, which 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. An integrated pointer on the mount indicates the setting of the graduated scale on the attenuator. Model 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. Circular Variable Metallic Neutral Density Filters are sold separately.
