Post and post holder sold separately.

The SV-0.5 Series Compact Adjustable Width Slit provides precise micrometer-driven adjustment of two blades centered equally about a 0.5-inch (12.7 mm) through-hole. The slit width ranges from fully closed to 0.20 inch (5 mm) and is designed so that the micrometer reading corresponds to the actual slit width. The slim profile of the mount and four face-plate mounting holes make it ideal for use with compact and OEM optical assemblies. An 8-32 (M4) threaded mounting hole located on the bottom of the unit is compatible with our standard mounting posts and pedestals.
