Optical Post, Slotted Base, 101.6 mm Height, 25.4 mm Diameter, M4

The M-PX-4 Forkless Optical Post has a unique internal slotted base allowing it to be directly mounted to an optical table without a clamping fork. The 16.0 mm long slot provides flexibility in positioning the post before securing it to one of the optical table's holes. This patent-pending feature saves 3X the space of a standard pedestal while still providing positional flexibility and long-term stability. This 25.4 mm diameter stainless steel post has a 101.6 mm height. Each post is marked with an index groove every 25.4 mm for a quick height reference. Cross-drilled holes allow 5.0 mm hex wrenches to aid in tightening and loosening assembled posts.
