Optical Pedestal, 101.6 mm Height, 25.4 mm Diameter, M4 Thread

The M-PS-4 Precision Ground Stainless Steel Optical Pedestal maintains long-term optical system alignment. This 25.4 mm diameter post has a 101.6 mm height. Each optical pedestal is marked with an index groove every 25.4 mm for a quick height reference. Cross-drilled holes allow 5 mm hex wrenches to aid in tightening and loosening assembled posts. An M4 threaded hole on each end allows pedestal posts and post extenders to be attached together end-to-end using a setscrew. In-between heights can be achieved by combining an optical pedestal with a 12.7 mm high post and/or spacers, available in 3.18 and 6.35 mm heights. For direct mounting to a threaded hole on an optical table, use a M6 to M4 thread adaptor. Optical pedestals enable ultra-stable mounting of optical mounts at low beam heights. Slotted clamping forks secure pedestals anywhere on an optical table. This product is also available in 10-piece saving pack M-PS-4-PK.
