The deflection under load is a measure of the stiffness of the optical table. The optical table supports used to support the optical table had a transmissibility less than 0.01 for frequencies greater than 10 Hz. The measurement reported in the specifications table was taken in a quiet laboratory environment (PSD <10 -9 g 2/Hz). The maximum relative tabletop motion is the worst case relative displacement for a rectangular optical table, the two points that produce the worst case results are generally located at the corners of the optical table. The relative tabletop motion is the relative displacement of any two points on the optical table surface due to environmental vibrations transmitted through the optical table supports. Nexus ® optical tables feature proprietary optimized damping mechanisms to limit the value of Q at the table's natural resonances. The maximum dynamic deflection coefficient is usually due to the response of the optical table at its first natural resonance frequency. Q is calculated by dividing the compliance at the optical table resonance frequency by the theoretical compliance of an ideal rigid body. Where Q is the amplification of the tables response to a vibrational source at a specific frequency ( f) of the optic table. Physically, the dynamic deflection coefficient can be interpreted as a measure of the table's motion when subjected to vibrations. The dynamic deflection coefficient is a figure of merit for optical tables that is derived from the measurement of the optical table's compliance.

Please contact Tech Support to order an optical table equipped with the necessary alterations. Please note: All tables require modification to accept earthquake restraints prior to shipment. We offer earthquake restraints for lab safety in earthquake zones and a selection of other optical table accessories. We also sell rigid table legs as well as legs with either active or passive isolators. We offer configurable, integrated, active and rigid isolation workstations (pictured below) with an extensive selection of accessories. Our optical tables require isolating supports (sold separately). See the Nexus Guide tab for a complete overview of the Nexus optical tables product line. Custom sizes and options are also available with a typical lead time of 6 - 8 weeks. Other sizes listed below are built to order with a typical lead time of 4 - 6 weeks. Popular imperial and metric table sizes are stocked in our US and UK warehouses, respectively, for immediate shipment. The table has 1/4"-20 (M6) mounting holes on 1" (25 mm) centers with a 1/2" (12.5 mm) border at the edge of the table.
