A tripod has an adjustable top plate that supports an equipment foot. The support legs each comprise paired plates. Interposed between the paired plates is a damping material. The damping material damps the tripod and inhibits resonance from passing through the tripod to the supported equipment.

Support tripod

A honeycomb tabletop where the upper skin has tapped holes formed therein. The tapped holes have a thickened portion at the a top surface of the skin and the tapped holes are characterized by depending extension formed integrally with the tapped holes. Threads are formed on the inner surface of the tapped hole including the sleeve. The depending sleeve effectively increases the number of threads to secure a fastener.

Lightweight honeycomb tabletop

An optical tabletop which has dampers located in the corners of an optical tabletop are each a suspended mass through which passes threaded rods. The suspended mass is submerged in a viscous liquid. Adjustment of the rods allows the optical tabletop to be tuned.

Accessible variable tuned damper assembly for optical table tops

A honeycomb tabletop for use with either a vibration isolation system or a rigid support stand. The tabletop has an upper skin, a lower skin, a connecting side wall, and a honeycomb core. Additional stiffening members and structural damping treatment may also, independently, be incorporated within the honeycomb core. The upper skin of the table has a plurality of tapped holes for mounting equipment. Each hole is sealed off from the interior of the table by a closed cavity enclosure which is secured to the underside of the top skin in registration with each hole. The cavity enclosures keep residue and contaminants from passing to the interior of the tabletop and facilitate cleanup of the tabletop. The enclosures are not subjected to any loads during use of the tapped holes in the top skin. The lower skin may optionally be perforated to prevent internal pressure buildup.
