This series of rigid support frames is designed to support optical breadboards in a laboratory or production environment where vibration isolation is not a critical factor. If needs change, these support frames can be easily upgraded to provide passive isolation using our PWA series passive upgrade kits.
Mobile Workstation Features
- Light Weight Aluminum Design
- Lockable Casters
- Four Adjustable Anti-Slip Support Pads
- Under Storage Tray and Optional Drawer
The Optics a la Cart is a mobile, non-isolating workstation, ideal for applications where an experiment needs to remain mobile before being moved to an optical table.
Our range of Nexus® Breadboards, including a line of non-magnetic breadboards are available separately.
Thorlabs non-isolating breadboard supports consists of a frame supported by four steel legs, with a rubber mount at the top which supports the breadboard. This rubber mount is attached to the supporting leg by a jack screw. Using an open ended wrench, these jack screws can be adjusted to level the breadboard or adjust the height over a ±15 mm (0.6") range.
Please see the Vibration Isolation Tutorial for more information the design of our products and the theory of vibration isolation and damping.
Selecting a Vibration System
Thorlabs offers three types of breadboard support systems: Active Isolation, Passive Isolation and a rigid support system.
The Active and the Passive isolation systems are both based on compressed air, providing vibration isolation in frequencies above 2Hz and 10Hz (respectively) making them ideal systems for demanding photonic experiments or for work in a noisy environment. In addition, Thorlabs also offers rigid support systems with no vibration isolation for less demanding applications which require only breadboard isolation. The table below compares the isolation performance of our different isolation systems.

Vibration Isolation
Vibration isolation is needed to isolate between noises originating around the workstation and breadboard surface. Such vibrations may result from machinery in the building such as elevators or compressors, pedestrians, building vibrations and nearby street traffic. The role of the vibration system is to dampen, both horizontally and vertically, the noises generated by the surrounding environment. Such noises are typically in the range of 10-100 Hz. the table below depicts common vibration sources:
| Types | Frequency (Hz) | Amplitude (inches) |
|---|---|---|
| Air Compressors | 4 – 20 | 10-2 |
| Handling Equipment | 5 – 40 | 10-3 |
| Pumps* | 5 – 25 | 10-3 |
| Building Services | 7 – 40 | 10-4 |
| Foot Traffic | 0.5 – 6 | 10-5 |
| Acoustics | 100 – 10,000 | 10-2 to 10-4 |
| Punch Presses | Up to 20 | 10-2 to 10-5 |
| Transformers | 50 – 400 | 10-4 to 10-5 |
| Elevators | Up to 40 | 10-3 to 10-5 |
| Building Motion | 46/Height in meters | 10-1 |
| Building Pressure Waves | 1 – 5 | 10-5 |
| Railroad | 5 - 20 | +/-0.15 g |
| Highway Traffic | 5 - 100 Hz | +/-0.001 g |

(posted 2018-10-17 21:55:16.63) Hi, I have an older PFL51501 and am looking to replace the rubber pads on the bottom of the feet. I'm hoping the pads are the same as newer versions. Can you supply a part number for those? If need be I could buy four new feet in general but all I really need are the rubber pads themselves... Thanks. AManickavasagam
(posted 2018-10-18 03:45:42.0) Response from Arunthathi @ Thorlabs: Thanks for your query. I have contacted you directly with a quote for the rubber pads. jlow
(posted 2012-12-13 09:21:00.0) Response from Jeremy at Thorlabs: You are indeed correct with your calculation. The optimum minimal table deflection is at 0.554 x the length. The recommended frame size on the website is basically a compromise between aesthetics and performance. n.stroilov
(posted 2012-12-11 12:51:55.833) Hello
Could you please help me to choose right frame size for PBH52522.
Acordeing your table (http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=1871) frame should be 1500х900mm.
But we have always followed that for minumum table deflection, most optimal distance between supports should be 0.554 х L (where L is table lenght).
So according our calculations frame should be 1200х600mm. That frame we have bought for our tables.
Is it your table strength calculations does not confirm this? |

Installation of Passive Isolation Mount
- Supports a Wide Range of Breadboard and Optical Table Sizes
- Use Extra Mounts to Increase Load Capacity
- Supplied as a Set of Four
These Passive Isolation Mounts, which are designed for use with breadboards and small optical tables, are particularly well-suited for upgrading a rigid, non-isolating support frame. They can also be placed on a floor or benchtop to provide a quick and easy temporary vibration isolation solution when a permanent system is not deemed necessary.
The mounts are sold as a set of four, contain a Schrader valve, and can be inflated using our standard foot pump. Other quantities are available by contacting Tech Support. Please follow the instructions outlined in the installation guide so that the isolation mounts are neither overinflated nor underinflated.
