These Ø1" Post Holders are the ideal solution for mounting optical components when a specific height has not been determined. Our line of Ø1" Posts covers a range of fixed heights; however, these post holders allow more height flexibility while still using our Ø1" stainless steel posts. The stability provided by the RSH series of post holders is equivalent to that provided by either directly threading the post into the optical table or by utilizing a pedestal post with a clamping fork. A taller post holder should be used with a longer post in order to obtain the greatest stability. Please see the Stability Tab for more information.

The flexure design supports the post in a clamping mechanism that is secured with an 8-32 (M4) cap screw. The bore has two grooves: a circular groove and a square groove. The circular groove allows the metal to flex and clamp the post's position without breaking. The square groove provides two fixed contact lines for the post to ensure it will always be locked into the same place. These post holders have a pedestal base and can be easily secured to a breadboard or optical table using the PF175 clamping fork.

Clamping Fork


The PF175 clamping fork secures the RSH post holders to any breadboard or optical table.This clamping fork create three points of contact with the table for high stability.

Please note that significant overtightening of clamping forks can deform the surface of an optical table, which can cause misalignment of components and decrease stability of the clamping fork.


Our Mission is to accelerate the advancement of optical technology for precision measurements and their applications from the table tops of research laboratories to standard use in communication and high technology industries. Our aim is to serve our customers. Our hope is to create a place for highly skilled people in an open environment
