Stainless Steel Optical Posts: Ø1/2", Ø12.7 mm, and Ø12 mm
Removable 8-32 Threaded Stud
Available Individually in Lengths Ranging from 3/4" to 12"
Packs of 5 Also Available for 3/4" to 6" Lengths
These nonmagnetic stainless steel posts are precision ground to Ø1/2". One end has a 1/4"-20 tapped hole, while the other end has a removable 8-32 threaded stud. A side-located Ø0.13" (Ø3.1 mm) hole is bored straight through the post; a balldriver can be inserted through the hole to provide extra leverage when tightening mounted components. To reduce packaging waste, we offer our most popular sizes in packs of five.
Removable M4-Threaded Stud
Available Individually in Lengths Ranging from 20 to 300 mm
Packs of 5 Also Available for 20 to 150 mm lengths
These nonmagnetic stainless steel posts are precision ground to Ø12.7 mm. One end has an M6 tapped hole, while the other end has a removable M4-threaded stud. To easily distinguish these metric posts from their imperial counterparts featured above, the metric posts have an extra ring-shaped groove at the upper end of the post. A side-located Ø0.13" (Ø3.1 mm) hole is bored straight through the post; a balldriver can be inserted through the hole to provide extra leverage when tightening mounted components. To reduce packaging waste, we offer our most popular sizes in packs of five.
These are identical to our Ø1/2" TR posts above, but feature an engraved scale along their side. This scale provides a means to quickly and accurately align optics to your optical axis. A removable 8-32 (M4) mounting stud at the top of each post is compatible with many components such as fixed optic mounts, while a 1/4"-20 (M6) tap is on the other end of the post for mounting larger components.
Removable M4 Threaded Stud
These nonmagnetic stainless steel posts, which are especially designed for our Japanese customers, are precision ground to Ø12 mm. The Ø12 mm Posts are compatible with our PH-Series of Post Holders and all Ø1/2" TR related products. One end has an M6 tapped hole, while the other end has a removable M4-threaded stud
0.04" (1 mm) Travel per Revolution of Adjustment Ring
Anti-Backlash Spring Design
Lockable Design with Non-Rotating Tip
The TRT2 translating post has been designed to provide quick, stable height adjustment of a mounted component within an optical setup. Utilizing a knurled collet, the TRT2 can translate ±0.13" (±3 mm) from its nominal position via 0.04 (1 mm) translation per revolution. When fully compressed, the post is 2.01" (50.1 mm) and a maximum length of 2.26" (57.4 mm). Once the desired height is achieved, the TRT2 can be locked into place with a locking ring. Both the adjustment collar and locking ring have diameters slightly smaller than the post diameter, allowing the entire post to pass through all of our Ø1/2" construction accessories without interference.

Side-Mounted KM100 Rests Flat on TR3T
These TR posts are designed for mounting optomechanical components in non-standard configurations. By using a combination of a tapped construction post along with a counterbored construction post, components can be mounted at an arbitrary angle to keep your beam path unobstructed. The TR3C (TR75C/M) offers five #8 (M4) counterbores and a mounting flat while the TR3T (TR75T/M) offers three 8-32 (M4) tapped holes and a mounting flat. The posts can be combined by using an 8-32 (M4) cap screw. Additionally, a single post may be used to mount an optomechanical component on its side using the mounting flat on each post (see image to the right).
