MB12 - Aluminum Breadboard, 12" x 12"
These solid aluminum, nonmagnetic baseplates provide a convenient and cost-effective platform for assembling prototype optical assemblies, conducting experiments, and mounting small subsystems. They are finished with a black, minimally reflective anodized coating and are through-drilled with a standard 1" (imperial) or 25 mm (metric) hole pattern offset 1/2" or 12.5 mm, respectively, from the edges of the board. The holes are threaded completely through these breadboards, allowing components to be mounted on both sides at once. Breadboards are offered in either 1/2" or 3/4" thicknesses.
Each breadboard features four or five mounting holes that are offset from the array of 1/4"-20 (M6) threaded holes to create an uninterrupted surface for any intended application. The four standard mounting holes are located at each corner of the breadboard, inset 1" from each edge (25 mm on metric). The larger imperial and metric breadboards have a fifth counterbored mounting hole at the center of each board (imperial boards 18" or wider, metric boards 450 mm or wider). Utilizing the center mounting hole increases the mounting options available, reduces stress at the corner mounting holes, and increases rigidity when heavy loads are placed on the boards. The mounting holes may be used to attach the breadboards to variety of surfaces and mounts, including optical tables, other breadboards, mounting posts, and brackets.
