Optical Tables Shelves, Free-Standing
Cable Racks Available Separately
Overhead Shelving Unit
Thorlabs' Free-Standing Instrumentation Shelves provide two levels of storage space or mounting surfaces for instruments, power supplies, and other accessories. As a free-standing unit, the operation of the table's vibration isolation system is not affected. Three shelving units are available for compatibility with 2.0 m (6.5'), 2.5 m (8.2'), or 3.0 m (10') long optical tables. The shelf units are also compatible with all of our table supports, including our optical table workstations. The PTA280 and PTA281 each come with two 598 mm (23.5") wide Melamine-faced MDF (medium density fiberboard) shelves (one per level) that can each support up to 135.0 kg (297 lbs). The PTA282 comes with two 598 mm (23.5") wide Melamine-faced MDF shelves per level; each level can support up to 122.0 kg (269 lbs).
The vertical steel support struts 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 solid aluminum breadboards when using the optional mounting brackets (detailed below). Furthermore, the underside of each shelf is fitted with threaded inserts to allow our power distribution strips, LED light strips, and cable racks to be attached. Lean bars and a post-mounting adapter also facilitate the attachment of post-mounted accessories, such as a monitor mount. These accessories are shipped with all necessary hardware and are described in detail below.
These Side Lean Bars span the entire width of the optical table on the right or left side. They are sold as a package of two to fit one end of the table. The bars bolt to the support struts of the overhead shelf described above and shield the vibration-isolated tabletop from accidental contact. Once fitted, they allow our selection of our post-mounted Nexus table frame accessories to be used (see table to the right).
The TFA4 Post Adapter allows you to attach post-mounted accessories to the free-standing overhead shelf's uprights. As shown in the photo to the right, the adapter is bolted to one of the uprights using two supplied M8 bolts. Once connected, the 75 mm (2.95") long Ø1.5" post can be used to attach various accessories, such as, such as our monitor mount, instrument shelves, breadboard brackets, or component trays.
These 24-outlet, power strips are available with US-, EU-, or UK-style outlets. Each is designed for indoor use and is housed within an impact-resistant, sturdy metal case. They are fitted with clearance holes for standard 1/4"-20 or M6 cap screws for direct attachment to the underside or side edge of the shelving frame. The units are turned on and off with a rocker switch.
The HDPS24-UK 24-Outlet Power Strip is installed on the front of the overhead shelf of a free-standing shelf unit. It can also be installed to the underside of the shelf.
These rigid LED light strips are available in two lengths: 850 mm (33.46") or 1828.5 mm (71.99"). They are held in place by three spring clips that are easily fitted to a rack or a shelf, such as our Free-Standing Overhead Shelf or our Nexus Table Frame Overhead Shelves. The strip lights can also be mounted over a bench for general laboratory use.

The two shorter trays are supplied with two mounting brackets, while both the longer racks are shipped with three brackets.
