The sliding post collar from LBTEK is secured to a Ø12.7 mm post using a socket knurled thumb screw. After placing the post into the post holder and coarsely adjusting it to the desired height, slide the post collar onto the post until its bottom contacts the top of the post holder. Tighten the knurled thumb screw to secure the post. For 10 mm fine adjustment of the post position within the post holder, use a 2 mm hex key to adjust the support height of the M3 screw on the upper surface.

The Ø12.7 mm post alignment collar assembly from LBTEK maintains post height and rotational orientation. It comprises two components: a post holder collar fixed to the post holder, and an OPRM-3 post collar. For optimal performance, tighten the thumb screw of the post holder against the post holder collar. The screw is positioned as correspondingly shown(see right diagram). When adjusting the rotational position of the post holder collar, the thumb screw on the holder should carry sufficient load to ensure dual-line contact between the post and the post holder. Both the post holder collar and post collar are secured using M4 screws.

The Ø12.7 mm post collar from LBTEK is secured to the Ø12.7 mm post via a set screw. The collar can be flexibly installed at the top of the post holder without affecting the height of the mounted device, and may also be used with the post holder collar in the OPRM-2 assembly to fix the rotation direction.

When optical components and their mounts require a flat surface during translation or rotation, the OPRM-4 contact block functions as an intermediate interface. The contact block supports posts to maintain height. It features five contact pads on the top, bottom, and sides for simple, flexible use. Mounted on the outside diameter of a Ø12.7 mm post, the OPRM-4 is secured with a side-mounted M4 rubber-tipped screw.

The OPRM-5 adjustable locator from LBTEK provides precise axial height positioning of posts. It incorporates a high-precision M5×0.25 hex adjuster, finely located via a 2 mm hex key. For extended or reduced ranges, this adjuster can be replaced with any M5×0.25 hex adjuster. The right diagram shows the adjustable locator mounted on the outside diameter of a Ø12.7 mm post for axial movement, secured by a side-mounted M4 rubber-tipped screw.

The OPRM-6 adjustable fixed stop block from LBTEK functions as a rotational stop block when used with the OPRM-4 contact block. Multiple stop blocks can be combined to construct reference edges. It is ideal for repeatable positioning of optical components in systems and scenarios requiring component replacement. A hardened steel ball at one end of the OPRM-6 provides single-point contact, while the stop block mounts on the outside diameter of Ø12.7 mm posts and is secured with a side-mounted M4 rubber-tipped screw.
