Optical Table Workstation for 1.2 m x 2.5 m x 310 mm (4' x 8' x 12.2") Tables![]()
TF1225A6 Nexus Table Frame Complete Workstation ![]() Please Wait Nexus® Optical Table WorkstationConfigurable and Integrated Our new Nexus® Optical Table Workstations adapt our large vibration isolation optical tables to incorporate many of the design innovations of the breadboard-based ScienceDesk workstations. We provide standard and optional accessories, and offer compatibility with ScienceDesk accessories so you can build a unique and integrated vibration isolation table workstation for photonics, imaging, and microscopy applications. Features
Thorlabs' Nexus® Optical Table Workstation, designed for 1.2 m x 2.5 m x 310 mm (4' x 8' x 12.2") optical tables, is a high-quality, ergonomic frame system that is compatible with a range of modular accessories, making it ideal for use in photonics applications. Each frame includes a removable under table shelf to keep lab equipment off of the floor and provide more space within the lab. Integrated casters with a leveling foot are also provided for easy mobility and placement within the lab. A complete Nexus optical table workstation consists of the active table frame, an optical table, and a range of user-chosen accessories. When used together these pieces form a versatile work space that can be customized to meet any need. Each frame has a height of 600 mm (23.6") for use with our 310 mm (12.2") thick optical tables to provide a constant working surface height of 910 mm (36"). They include active-air, self-leveling vibration isolators that isolate the tabletop from vibrations present within the lab with greater than 95% efficiency at 10 Hz (see the Frame Specs tab for full specifications). Please see the Isolators tab for more details about the active isolators. Environmental noise factors are as critical as the application when choosing a workstation. Our Technical Support department can provide a personalized recommendation based on your application and laboratory environment. Optical Table Accessories The lean bars also enable compatibility with post-mounted accessories and shelving. .

Optical Table Frame IsolatorsThorlabs' optical table frame for 1.2 m x 2.5 m x 310 mm (4' x 8' x 12.2") optical tables has isolator mounting platforms in each of the interior four corners. These platforms are fitted with active self-leveling isolators that provide the highest level of isolation available in the optical table line of workstations. Rigid support options that can be upgraded to have passive isolation are available with our optical table frames for 210 mm (8.3") thick optical tables. ![]() Active Supports
Our Workstations equipped with active isolators provide the highest degree of vibration isolation available. Vertical damping is achieved by the use of a dual-chamber, damped pneumatic spring. The table is supported by the air pressure in these chambers. A piston, in contact with the bottom of the optical tabletop, is sealed to the upper chamber with a rolling rubber diaphragm, allowing virtually friction-free motion between piston and chamber. Floor or tabletop motion forces air to flow from one chamber to the other through a laminar flow damper. This restriction of airflow damps oscillatory motion between the floor and table, dramatically reducing settling time. The volume ratio of the chambers has been optimized to minimize the resonant frequency of the table frame while maximizing the damping performance. Damping of horizontal vibrations is accomplished by supporting the pneumatic vertical isolator on a Trifilar suspension system. This innovative pendulum design uses gravity to provide the restoring force after horizontal disturbances. Horizontal oscillations at the system’s resonant frequency are damped by linking the base of the vertical isolator to the outer cylinder with an oil-free, vibration-absorbing damper. To allow for changes in load distribution, the active vibration isolation optical tabletop supports have a self-leveling system based on precision 3-way valves that do not compromise vertical isolation when the system is at rest. Because these valves are actuated by tabletop movement, the system returns to within ±0.5 mm (0.02") of its original level position after disturbances. These isolators require a constant supply of air, such as that provided by our compressor. Removing the air supply will disable the active isolation system, causing the optical table to rest securely on top of the legs. Our active optical table frames not only provide the highest level of isolation, but by incorporating self-leveling valves, they are also ideal for applications where the load placed on the optical tabletop is constantly changing. Typical applications include holography, optical lithography, and high-power optical microscopy. In addition, the active isolation is often chosen when the surrounding environment is less than ideal since the active isolators provide a higher level of isolation from floor vibrations.

This frame provides a compact, portable, and ergonomic workstation solution for optical tables. The active supports deliver our highest level of vibration isolation available, making this frame suitable for applications requiring sub-micron resolution. The isolators require a constant source of pressurized air, such as that provided by our compressor. In addition, this isolation system will adjust the pressure in each isolator to keep the optical table surface level, even when the distribution of weight on the optical tabletop is changed. Casters and a removable under table shelf are included. Each optical table frame contains active supports in each leg that deliver our highest level of vibration isolation available, making these frames suitable for applications with sub-micron resolution. The isolators require a constant source of pressurized air, such as that provided by our compressor. In addition, this isolation system will adjust the pressure in each isolator to keep the optical table surface level, even when the distribution of weight on the optical tabletop is changed. Please note that an optical table equipped with earthquake restraints cannot be used with an optical table frame. ![]()
Thorlabs' extensive Nexus™ optical tables product line features all-steel construction, excellent thermal stability, and damping optimized for each table size. The 5 mm thick stainless steel top and bottom skins have a precision-machined matte finish. These tables have either 1/4"-20 taps on 1" centers (Imperial) or M6 taps on 25 mm centers (Metric), with a 1/2" (12.5 mm) border at the edge of the table for maximum usable area. These tabletops are manufactured from magnetic steel with sealed or non-sealed holes as standard. No holes options are available as a custom order upon request. Please note that an optical table equipped with earthquake restraints cannot be used with an optical table frame. ![]()
The TFB25 Lean Bar fits to either the front or rear of the frame to form a barrier that shields the vibration-isolated tabletop and protects it from accidental contact. They also allow shelves and post-mounted accessories to be used (see table above). Individually sold, each lean bar ships as three pieces that need to be assembled by the end user. The lean bar bolts to two supports arms, which in turn are bolted to the table frame, one to each of the facing isolators. All necessary mounting hardware is supplied. If you are also interested in having your workstation equipped with side lean bars, please see the presentation immediately below this one. ![]()

If additional shelf space is required, this overhead shelf system, with two shelves, is an ideal solution. The shelves span across the length of the optical table and are a great space saver in the lab. The vertical supports feature a range of mounting points to allow height adjustment, and through holes are included in each corner of the frame for easy cable management. The shelves can be replaced with MB series breadboards when using the mounting brackets detailed below. ![]()

The PTA512, PTA513, and PTA514 are high-performance air compressors designed for applications demanding the highest quality air supply. They are self contained, lightweight, and compact, with minimal vibrations due to the very low noise emitted (30 dB at 1 m) from the compressor. The oil-lubricated pump unit is fitted with piston rings, thereby eliminating oil carryover to the air supply. These compressors deliver 50% more air than other silent compressors. They accept standard 6 mm outer diameter tubing, include an air regulator, filter, receiver tank with pressure gauge, safety valve, drain, and line pressure gauge. They are shipped with a power cord for the appropriate territory.
