Passivated Stainless Steel Breadboards
4" x 4"
4" x 6"
6" x 6"
Thorlabs' passivated stainless steel, 1/2" (12.7 mm) thick breadboards provide a stiff, magnetic, and vacuum-compatible surface for mounting small subsystems. Breadboards are through tapped in a standard 1" (imperial) or 25 mm (metric) hole pattern offset 1/2" or 12.5 mm, respectively, from the edges of the board. Four standard 1/4" (M6) mounting holes are counterbored to create an uninterrupted surface for your application.
The 1/4"-20 (M6) tapped holes are threaded completely through these breadboards, allowing components to be mounted on either side. The four standard mounting holes are located at each corner of the breadboard, inset 1" from each edge on imperial breadboards (25 mm on metric). Ø1.5" mounting posts can increase the height of these breadboards by securing them to the surface of an optical table (or another breadboard). The counterbored mounting holes allow for these breadboards to be attached to any of our non-magnetic aluminum breadboards, providing a means to use magnetic bases or other magnetic accessories. The mounting holes may be used to attached the breadboards to optical tables, other breadboards, mounting posts, brackets, or a variety of other surfaces or mounts.
These breadboards may also be used within a vacuum environment down to 10-6 Torr. After passivation, breadboards are double bagged in a clean environment to eliminate contamination when transported into a cleanroom. Gloves should be used when handling breadboards to prevent surface contamination from skin oils. For use in a sensitive vacuum system, a thorough pre-baking in a bake-out oven should be performed to remove all moisture and surface volatiles. Additional cleaning may be needed depending on the system requirements. For additional information on preparing these breadboards for vacuum applications, please contact Tech Support.
Custom sizes up to 12" x 24" (300 mm x 600 mm) are available; contact Tech Support for more information. We also offer a broad selection of solid aluminum breadboards, steel and aluminum honeycomb breadboards, as well as a clear acrylic breadboard. For vacuum chamber applications, unanodized solid aluminum breadboards are also available in a variety of sizes. For a quick comparison of our different breadboard options, please see the BB Selection Guide tab.
