Features

Swivel Clamp Allows for Easy and Fast Alignment

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. 

Magnet in Base for Rough Alignment

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.

Brake-shoe Design Offers Grip for Easy Adjusting

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.

Two-Line Contact for Greater Stability

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.
