Optical Pedestal, 4.0 in. Height, 1.0 in. Diameter, 8-32 Thread

The PS-4 Precision Ground Stainless Steel Optical Pedestal maintains long-term optical system alignment. This 1.0 in. diameter post has a 4.0 in. height. Each post is marked with an index groove every 1.0 in. for a quick height reference. Cross-drilled holes allow 3/16 in. hex wrenches to aid in tightening and loosening assembled posts. An 8-32 threaded hole on each end allows optical pedestals and pedestal extenders to be attached together end-to-end using a setscrew. In-between heights can be achieved by combining a pedestal post with a 1/2 in. high post and/or spacers, available in 0.125 and 0.25 in. heights. For direct mounting to a threaded hole on an optical table, use a 1/4-20 to 8-32 thread adaptor. Optical pedestals enable ultra-stable mounting of optical mounts at low beam heights. Slotted clamping forks secure optical pedestals anywhere on an optical table. This product is also available in 10-piece saving pack PS-4-PK.
