Swivel Clamp optical post holders provide a continuously adjustable height to standard optical rods with the addition of a spring-loaded, break-shoe design to prevent slipping while making adjustments. The swivel base clamp and magnetic base make alignment quick and easy.

The swivel clamp allows for easy and fast alignment to the holes in an optical table. The stiff stainless steel base and swivel clamp provides superior stability to all aluminum designs.
The base of the swivel clamp incorporates a ring magnet, which allows for rough alignment prior to securing with the swivel clamp. The magnet is large enough to allow the post to pass through, so the post can rest directly on the optical table for maximum height adjustment.
VPH Series optical post holders feature a unique, spring-loaded, brake shoe design to apply constant friction to optical posts during height adjustments for no-slip operation, before locking in place with its thumbscrew. Unlike typical spring-loaded post holders, the VPH Series holds posts in place even if the thumbscrew is partially or completely loosened. Moreover, the VPH Series' holding force is greater than typical spring-loaded screws. The result is easier, faster, and more reliable alignment of an optical experiment.
By using precision machining techniques to remove a small portion of the interior surface opposite the set screw of our VPH Series optical post holder, two lines of contact are created with a post when it is pushed in by the screw. These two lines of contact provide greater stability compared to a post held in place against another circular surface.
