Optical Post Collars
Optical post collars enable fast and easy rotational adjustment and removal and replacement of optical posts at a repeatable height. By clamping the C-shaped collar to 0.5 in. (12.7 mm) posts where they contact an optical post holder, a height index is created without having to remove the post from the post holder. The collars secure in place with either a set screw or hand adjusted knob.

Replacement & Re-alignment is Easier with Height Indexing

Indexing height permits removal and replacements of posts at a repeatable height, reducing their realignment demands to rotational adjustments. The open-ring design of these post collars allow their removal and replacements without having to remove the post from the post holder.
Insertable Design for Easy Installation or Removal
The unique open-ring design of these optical post collars allow their attachment or removal without disturbing the optical post at all or alignment of mounted components. These collars lock in place easily by hand around 0.5 in. (12.7 mm) diameter posts and are available in sets of five.
