![]() Tables, once they are manufactured and shipped, cannot be retrofitted to accept earthquake restraints. Please contact Tech Support to order an optical table equipped with the necessary alterations. All tables require modification to accept earthquake restraints prior to shipment. Please note: We also offer earthquake restraints for lab safety in earthquake zones. For all table kits sold on this page, kits ending with HK and CK are paired with our PTS603 700 mm (27.5") tall legs, and kits ending with WK and QK are sold with our PTS602 600 mm (23.6") tall legs. If the source of compressed air is removed, the optical table will lower until it securely rests on the large-diameter cylindrical optical table supports, albeit the table will no longer be isolated from floor vibrations. The vertical vibrations are isolated from the optical table by a dual-chamber pneumatic isolation system that requires a constant source of compressed air, such as an air compressor (sold separately). ![]() ![]() Thorlabs' active vibration isolation optical table supports contain an isolation system that effectively isolates the optical table from vertical and horizontal vibrations throughout the critical 3 to 50 Hz frequency range since most common large-amplitude sources of vibrations found in laboratories vibrate within this range of frequencies. Optional sealed mounting holes are available. The table has 1/4"-20 (M6) mounting holes on 1" (25 mm) centers with a 0.5" (12.5 mm) border at the edge of the table. The 5 mm thick stainless steel top and bottom skins have a matte finish and the top skin is precision-machined with a surface flatness of ☐.1 mm over any 1 m 2 area. Nexus tabletops feature all-steel construction, excellent thermal stability, and broadband damping optimized for each table size. They are paired with 600 mm (23.6") or 700 mm (27.5") tall legs for a standard 910 mm (35.8") tabletop height. Kits are available with table sizes from 4' x 6' (1.2 m x 2 m) to 4.8' x 10' (1.5 m x 3 m) and table thicknesses of 210 mm (8.3") or 310 mm (12.2"). Thorlabs' Nexus ® optical table kits feature our Nexus optical tabletops and our active isolation table legs. For Use with Earthquake Restraints, Custom Order a Modified Table (Contact Tech Support).1/2" (12.5 mm) Hole Border for Maximum Usable Area.Every Table Individually Optimized, Tested, and Shipped with Test Data Certificate.Table Sizes from 4' x 6' (1.2 m x 2 m) to 4.8' x 10' (1.5 m x 3 m) Available.Bundle Includes Nexus Optical Table and Active Isolator Table Legs.See the Nexus Guide tab for a complete overview of our optical tables product line. See the Vibration Isolation and Construction tabs for more details. Each size is individually optimized, and each table ships with a unique test data certificate. They are suitable for photonics, imaging, and microscopy applications and provide quality and vibration isolation performance that exceeds the highest level of our former product line. Nexus is a single high-quality grade of tables and breadboards manufactured in various sizes by Thorlabs.
