Reduce Time to Construct Assemblies
Spring-Loaded Thumbscrew Secures Post Prior to Final Locking
Universal Post Holders Provide a Swiveling Clamping Fork and Magnetic Base for Easy Alignment

Thorlabs' Ø1/2" Universal Post Holders simplify the task of mounting a Ø1/2" optical post on an optical table or breadboard. These post holders incorporate a swiveling base, allowing a choice between multiple mounting holes on the breadboard. Magnets in the bottom of the base aid in rough alignment prior to final positioning. Additionally, the base is hollow, which allows the post to rest on the optical table and enables maximum height adjustment.

These Universal Post Holders have been designed with the same key features of our popular Standard Post Holders. They feature and extra wide square relief cut machined vertically along the length of the part, as shown in the drawing to the right. This channel provides a highly-stable two-line contact between the post and post holder. Other post holder designs that do not have a relief cut provide less holding power, which leads to a downward drift in the post's position with time. Each post holder comes with a 3/16" (5 mm) hex spring-loaded thumbscrew. Additional quantities can be purchased separately below.

Response from Tim at Thorlabs: Thank you for your feedback. The TR50/M will be able to fit in the UPH2/M and you will be able to adjust its height with the thumbscrew. However, because the length of the post is shorter than the length of the post holder, the TR50/M will be under the top of the UPH2/M when sitting near the bottom. If this is a concern, we do offer shorter UPH at http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1982&pn=UPH1 and taller posts at http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1266.

TR50/M (50 mm) is compatible with UPH2/M(50.8 mm) or not? Is it possible to use TR50/M (50 mm) with UPH2/M(50.8 mm)? Thank you.

The universal post holder is a component I personally highly recommend. No need to find a clamp, no need to change everything when you realize youre not right in front of the hole, magnets give a certain stiffness while allowing to move the optics parallel to the table : setting up an experiment suddenly becomes twice easier!
