Optical Post Holder, No Slip, 1.0 in. Height, 0.5 in. Posts, 1/4-20
Model: VPH-1
Product Series Overview
Standard Optical Post HoldersThe VPH-1 Standard Optical Post Holder has a 1.0 in. height, and a spring-loaded brake shoe design which applies a constant force to 1/2 in. diameter optical posts even when the thumbscrew is loosened. This allows the orientation of an optical mount to be easily adjusted with one hand. This post holder is designed for standard posts, and has a 1/4-20 threaded hole in it's base.
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.
