Stainless Steel Breadboard with Vacuum Compatible Components
Features
- Passivated Stainless Steel Breadboards
- Vacuum-Compatible Down to 10-6 Torr Out of the Box
- May be Attached to our Aluminum Breadboards to Add Magnetic Capabilities
- Standard Imperial (1/4"-20) and Metric (M6) Breadboard Hole Patterns
- Offset Counterbored Mounting Holes Allow a Full, Uninterrupted, Threaded Hole Matrix
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 are available; contact Tech Support for more information. We also offer a broad selection of solid aluminum breadboards and steel and aluminum honeycomb breadboards. 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.

 (posted 2019-09-11 15:25:22.53) Hello, this is a nice addition to your product line and I've ordered one of these. However, for the use case of adding magnetic functionality to an aluminum breadboard, may I suggest you offer a thinner version of these breadboards? You could for example use the same 5 mm thickness as your Nexus series steel skin. The newly designed steel breadboard could be blank with just 4 mounting holes to attach to an existing breadboard or have a set of clearance holes with the same spacing as metric or imperial breadboards. This design would be more economical for your customers and serves the useful purpose of having a magnetic flat surface. llamb
