Abstract
A low-profile, vibration-damped tabletop for supporting sensitive scientific equipment is described. The tabletop may include a laminated structure having a lower metal plate that is sized to achieve a desired weight for the tabletop, a manufactured, homogenous filler and a “clean top” metal upper skin having a plurality of holes backed by liquid impermeable barriers. The damping characteristics are improved at low frequencies compared to a comparable structure with a honeycomb filler.
