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.
Passive Upgrade Kit for Rigid Non-Isolating Supports
As applications develop and grow, vibration isolation requirements may change. The PWA076 kit sold below allows users to upgrade non-isolating supports so that they provide passive isolation. The upgrade kit contains four passive isolation units (one for each support) and all needed accessories; click on the red Docs icon (
) by the rigid leg item numbers below to download the installation manual. Please note that when the passive upgrade kit is fitted, the load capacity of the four supports is reduced to 1100 kg (2425 lbs). A heavy-duty upgrade kit, with a load capacity of 550 - 2200 kg (1200 - 4850 lbs), is available upon request.
| Feature | Design |
|---|---|
| Leveling System | Adjustable Support with Rubber Support Pad: The optical table can be raised 15 mm (0.59") or lowered 8 mm (0.31") by adjusting the height of the leveling support with an open-ended wrench for a total height adjustment range of 23 mm (0.90"). The height can then be locked into place using the locking nut. |
| Stable Support | Large-Diameter Cylindrical Design: The large-diameter, free-standing optical table supports provide maximum stability and safety. In addition, the adjustable rubber support pad ensures that the levelling mechanism remains in firm contact with the optical table and does not walk off the optical table supports over time. |
| 910 mm Working Height | Cylindrical Steel Supports: To complement our three table thicknesses of 210 mm (8.3"), 310 mm (12.2"), and 460 mm (18.1"), our optical table supports are available at heights of 700 mm (27.5”), 600 mm (23.6"), and 450 mm (17.7") to produce a working height of 910 mm (35.8”). |

(posted 2021-11-30 15:59:45.483) I want to buy the PTL803 legs for a Newport's Honeycomb Optical Breadboard (750 x 1500 x 110 mm, M6). I want to confirm that the legs will be compatible. Is it enough with putting the breadboard on the top of the legs without any special installation? Thank you. DJayasuriya
(posted 2021-11-30 10:40:47.0) Thank you for your inquiery. Yes the PTL803 will be compatible with Newport's Honeycomb Optical Breadboard (750 x 1500 x 110 mm, M6). Ye, correct, the weight of the optical breadboard will hold its position without any installation. kedves
(posted 2016-04-13 20:06:44.31) Hello, I would like to ask whether it would be possible to buy 2 pieces (instead of 4) of these rigid table supports? msoulby
(posted 2016-04-14 09:24:52.0) Response from Mike at Thorlabs: Yes it is possible to buy only two of these supports, your local Thorlabs office will contact you with a more details shortly. john.restrepo
(posted 2013-10-02 18:09:32.473) Greetings. I wonder if these rigid supports could be upgrade to have a passive isolation system, though, serveral months after the purchase. Is this significantly more expensive than buying the passive isolators in the first place?
Thanks very much.
John. jlow
(posted 2013-10-02 15:25:00.0) Response from Jeremy at Thorlabs: The rigid table support legs cannot be easily upgraded to have the passive mounts put in. It is easier and much cheaper to get the passive isolators in the first place. I will contact you directly to discuss more about this. Thorlabs
(posted 2010-07-21 10:47:38.0) Response from Javier at Thorlabs to jikim: Thank you for your feedback. The PTL602 set includes 4 rigid legs. jikim
(posted 2010-07-21 11:32:40.0) I have a silly question. Does a PTL602 include 4 pieces of posts or just 1 piece? |

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.
