VPH-2 In Stock

The VPH-2 by Newport is an advanced Optical Post Holder renowned for its innovative spring-loaded brake shoe design. This unique design ensures the application of a consistent force, even when the thumbscrew is disengaged. This feature guarantees that the optical mount can be effortlessly oriented using just one hand, without the risk of any slipping. With a height of 2 inches and a diameter of 1/2 inch, this post holder offers a compact yet robust solution for optical mounting needs. The base of the VPH-2 is equipped with a 1/4-20 threaded hole, adhering to the standard post specifications for seamless compatibility. This post holder can be directly threaded into an optical table or employed with either a slotted base or a pedestal base adapter. This adaptability permits mounting at various positions on an optical table according to specific requirements. A notable feature of the VPH-2 lies in its precision machining techniques including the removal of its set screw opposite of the small portion of the interior surface. This deliberate action facilitates the creation of two distinct lines of contact when the set screw is engaged. This results in significantly heightened stability compared to traditional methods where a post is secured against a circular surface. Furthermore, this post holder boasts open-ring post collars that can be effortlessly added or removed whenever necessary.
