Features

  • Black Anodized Solid Aluminum Construction
  • Metric Boards Manufactured & Stocked in Europe
  • Counterbores for Mounting Breadboards
  • Same Hole Pattern as Our Circular Optical Breadboards

Our Double Density Breadboards are constructed from a 1/2" (12.7 mm) thick aluminum plate to maintain flatness over the full length and provide a double density hole pattern of 1/4"-20 (M6 × 1.0) tapped holes (see the Hole Patterns tab for information on tap spacing). The small footprint and slim profile make these breadboards ideal for compact areas. Since the holes are threaded completely through these base plates, components can be mounted on both sides at once. Standoff posts allow the breadboards to be mounted above the surface of an optical tabletop (or breadboard), as shown in the image to the far right, for access to components on both sides.

Each breadboard features four or five mounting holes, offset from the array of 1/4"-20 (M6) 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). All breadboards except the MB12D, MB1530/M, and MB3030D/M include a fifth counterbored mounting hole at the center of each board. Using 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 (see photo to the right). 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.

One imperial and one metric breadboard below are designed for use with the EC2530C enclosure. They are thinner than the other breadboards on this page, and the mounting counterbores are positioned to allow the breadboards to be mounted within the enclosure. See our benchtop enclosures for custom electronics for details.

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

Note: the hole patterns on the EC2530BB and EC2530BB/M are different from those shown in the drawings above. See the following PDF drawings for details:

Greetings. I just thought you should rename these parts because it is not correct. It is called "double density" but is actually not twice the density of a standard breadboard. I think it is a bit misleading so why not change the name to high-density.

Response from Mike at Thorlabs: Thank you for your feedback. We use many factors in deciding how to name our products, one being industry trends, to be sure that our customers can find products using the most common names. Though there is not exactly two times the amount of holes, the tapped mounting holes have a spacing of 0.5” instead of the 1” spacing used in our standard breadboards. The number of tapped holes in each breadboard can be found in the support drawing which can be found by clicking on the red “Docs” icon by the item number. We will keep your feedback in mind as we continue to monitor trends and consider changes to the presentation for this product line in the future.

Is it possible to easily drill into these breadboards for example to allow a periscope to go through or do they have some sort of honeycomb structure inside them? Is it possible for you to make custom sized holes into standard sized breadboards? Cheers!

Response from Jeremy at Thorlabs: The MB series breadboards are solid aluminum breadboards with no honeycomb structure in them. It is fairly easy to bore a hole through these breadboards. We can custom make these with different size holes in the middle. We will contact you for some details and a quote.

Hi. I am Cheol-Joo Kim in Cornell university. Can I get a quote for a 4' wide x 10' long solid aluminum breadboards with double density holes? May I call it "MB410"? Is it possible to get? Thank you.
