This series active vibration isolation Optical Tables are offered in a variety of lengths and widths from 3000 mm x 1500 mm to other custom bigger size. They feature all-steel construction, excellent thermal stability, and broadband damping optimized for each breadboard size.


The 5 mm thick stainless steel top and bottom skins have a precision-machined matte finish with surface flatness of ±0.1 mm over any 1 m2 area. The optical table has M6 mounting holes on 25 mm centers with a 37.5 mm border at the edge of the breadboard.


This active vibration isolation optical table supports contain an isolation system that effectively isolates the optical table from vertical and horizontal vibrations. The vertical vibrations are isolated from the optical table by a pneumatic isolation system that requires a constant source of an air compressor. The horizontal vibrations are isolated from the optical table by mounting the vertical isolation system on a trifilar suspension system.


Each optical table support is also equipped with a 3-way valve. The valve regulates the pressure in the pneumatic isolation system to control the height of the optical table. If the table is displaced vertically, the 3-way valve will allow the pressure in the air reservoir to increase or decrease, as necessary, so that the table is returned to its original height.
