ScienceDesk™ Workstations for 2.5' x 3' (750 mm x 900 mm) Breadboards

Click to Enlarge
Standing Height Active Isolation ScienceDesk with Breadboard Fitted

• Three Support Options:
  • Active, Self-Leveling Vibration Isolation (SDA7590 and SDA7590S)
  • Passive Isolation (SDP7590 and SDH7590)
  • Rigid, Non-Isolating (SDR7590)
• Welded Steel Frame (No Assembly Required)
• Easy to Relocate with Optional Casters
• High Load Capacities up to 700 kg (1540 lbs) (See Specs Tab for Details)

These frames provide a compact, portable, and ergonomic workstation solution for optical breadboards. The breadboard rests within the frame bars, which also protect the worksurface from incidental contact and provide compatibility with a number of additional accessories such as monitor mounts, keyboard holders, and shelving. The welded steel frame provides high rigidity and requires no assembly. Optional casters provide easy mobility throughout the lab while a large array of shelving, storage, lighting, and computer accessories create an ergonomic, modular workspace ideal for any application.

Our active-isolation ScienceDesks are available in two heights, 765 mm (30.12") and 910 mm (35.80"). The shorter desk (SDA7590) is optimized for comfort while in a seated position, while the taller one (SDA7590S), shown to the right, is designed as a standing desk option with clearance to comfortably fit a lab stool with ample leg room. The height of all desks can be adjusted by ±15 mm (±0.59") using leveling feet.

Support Options
These ScienceDesk Workstations are available with active, passive, or non-isolating supports depending on the amount of vibration isolation needed. Our active supports deliver our highest level of vibration isolation making them suitable for applications requiring nanometer resolution. In addition, they will adjust the pressure in each isolator to keep the optical table surface level, even when the distribution of weight on the tabletop is changed. Active supports will require a constant source of pressurized air, such as that provided by our compressor. For less demanding applications that require sub-micron resolution, such as OCT and confocal imaging, we offer passive isolation supports. Passive isolation supports do not require a constant source of compressed air and can be inflated with a simple air pump, but please follow the installation instructions outlined in the user guide so that the isolators are neither overinflated nor underinflated. Finally, a non-isolating rigid support frame is available that is ideal for applications that do not require vibration damping.

For more information on the different isolation types, please see the Isolators tab above.

Thorlabs' 2.5' x 3' (750 mm x 900 mm) Breadboards for our ScienceDesk Workstations feature steel construction and excellent thermal stability. Two options are available based on the amount of vibration damping required on the tabletop: our Nexus breadboards with opimized vibration damping and our intrinsically damped breadboards with minimal vibration damping. See the table to the right for more information on the different options.

Nexus Breadboards
Nexus Breadboards are the ideal choice for minimizing vibrations created on the work surface. They are designed to have broadband damping optimized for their size and feature all-steel contruction. They are available with 1/4"-20 (M6 x 1.0) mounting holes on 1" (25.0 mm) centers with a 0.5" (12.5 mm) border at the edges, no mounting holes, or with sealed mounting holes for liquid spill management. A 1/4"-20 (M6 x 1.0) tapped breadboard that is constructed from 304L nonmagnetic steel is also available. Every Nexus breadboard is individually optimized, tested, and shipped with a test data certificate.

Intrinsically Damped Breadboards
Our intrinsically damped breadboards are available for applications requiring minimal vibration damping on the tabletop. They have a steel top plate, bottom plate, and honeycomb core with side panels that are created from unplasticized polyvinyl chloride (uPVC). The breadboard has 1/4"-20 (M6 x 1.0) mounting holes on 1" (25.0 mm) centers with a 0.5" (12.5 mm) border at the edge.

Custom options are available with a typical lead time of 6 - 8 weeks. Please contact Tech Support for more information.
