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.

Each breadboard features four or five mounting holes, offset from the array of 1/4"-20 threaded holes, which are counterbored 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: MB1218 through MB2448; metric: MB1560/M through MB15120/M, and MB3045/M through MB60120/M). 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 optical tables, other breadboards, mounting posts, brackets, or a variety of other surfaces or mounts. Please see the Mounting Options tab for more details.

Because the holes are threaded completely through these breadboards, components can be mounted on both sides at once. Ø1.5" Mounting Posts allow for adjustments to the height of the optical axis by mounting the breadboards above the surface of an optical tabletop (or another board). The breadboards can also be mounted vertically using 90° or Vertical Mounting Brackets.

For vacuum applications, we recommend using our selection of Unanodized Breadboards.

Other Breadboard Options
Optical Breadboard Enclosures are available to protect sensitive equipment from dust, stray light, acoustic noise, and thermal variations. Enclosures are offered completely sealed or with sliding door access.

Thorlabs also offers SlimLine Double Hole Density Aluminum Breadboards with 1/2" offset hole spacing, doubling the density of mounting holes. These are offered in sizes ranging from 4" x 24" to 8" x 36" (100 mm x 600 mm to 200 mm x 900 mm) with thicknesses of 0.5" (12.7 mm), making their slim profile ideal for compact work areas.

For limited space applications, Thorlabs offers the MS12B and MS12B/M Mini-Series Breadboards. These breadboards feature increased tapped hole density and thinner breadboard thickness.


Our Mission is to accelerate the advancement of optical technology for precision measurements and their applications from the table tops of research laboratories to standard use in communication and high technology industries. Our aim is to serve our customers. Our hope is to create a place for highly skilled people in an open environment
