All rigid supports can be upgraded to passive isolators. Simply remove the rigid pad using the included wrench, and then secure the PWA076 Passive Isolation Upgrade Kit.
Thorlabs' Rigid, Non-Isolating, free-standing Optical Table Supports are strong enough to support an optical table under heavy load. Each support has an adjustable pad to level or adjust the table height over a 23 mm (0.90") range using the included 24.0 mm (0.94") open-ended wrench. The height can then be locked in place using the included 36.0 mm (1.42") open-ended wrench. These supports can be used with any of our optical tables.
When paired with a Nexus® series optical table and a quiet environment, vibration-insensitive photonics experiments like general spectroscopy and multimode fiber coupling can be performed. A set of four supports is capable of supporting loads up to 2500 kg (5500 lbs) and full installation instructions are included. More than four supports may be necessary for higher loads, long tables, or custom-designed joined systems. Please contact Tech Support to discuss your specific requirements.

Optical Table Legs
Thorlabs' Rigid, Non-Isolating Optical Table Supports can be used with all of our optical tables and are ideal for vibration-insensitive photonics experiments like general spectroscopy and multimode fiber coupling. A set of four isolators is capable of supporting loads up to 2500 kg (5500 lbs) and full installation instructions are included. More than four isolators may be necessary for higher loads, long tables, or custom-designed joined systems. Please contact Tech Support to discuss your specific requirements.
Each leg is adjustable over a 23 mm (0.90") height range and has a non-slip rubber pad; height adjustements are made using the supplied open-ended wrench. More information about the function and construction of the optical table supports can be found under the Design tab on this page or in the Isolation Systems tab of the Optical Tables Tutorial.
The PWA076 Passive Isolation Upgrade Kit allows the PTL701, PTL802 or PTL803 Rigid, Non-Isolating Supports featured above to be upgraded to passive isolation. The mounts are easily fitted in place of the existing support pads (click on the red Docs icon () by the rigid leg item numbers above to download the installation manual) and can be inflated using a standard foot pump. Supports with serial numbers prior to 200018 may be difficult to upgrade; contact Tech Support for more details.
Thorlabs' passive isolators are designed to remove floor vibrations in the critical 10 Hz to 50 Hz frequency range. The passive air mount design is ideal for most general optical table uses, providing low frequency isolation coupled with excellent stability in both horizontal and vertical directions. Please follow the instructions outlined in the installation guide so that the isolators are neither overinflated nor underinflated.
Note that the PWA076 has a maximum load capacity of 1100 kg (2425 lbs). Contact Tech Support for options with higher load capacity.
