These breadboards feature a tapped hole pattern aligned at 45° compared to traditional aluminum breadboards. The 45° hole matrix is laid out as a double-density matrix with the tapped holes on 1" (25 mm) centers, allowing optomechanical components and bases with standard 1" mounting hole spacing to be mounted to these breadboards as shown in the image to the far right.

Each breadboard features four counterbored mounting holes aligned with the standard 1" (25 mm) spacing on traditional optical tables and breadboards. The mounting holes are located at each corner of the breadboard, inset 1" from each edge (25 mm on metric). These counterbored mounting holes may be used to attach the breadboards to variety of surfaces and mounts, including optical tables, other breadboards, mounting posts, and brackets.

The chamfered corners serve to visually distinguish these breadboards from traditional breadboards. These 1/2" (12.7 mm) thick breadboards are finished with a black, minimally reflective anodized coating, and the holes aligned at 45° are threaded completely through, allowing components to be mounted on both sides at once.

Custom Breadboards
We offer a service for custom breadboard orders, with options that include hole pattern and spacing, size, thickness, and anodizing. For a quote, please contact Tech Support.

    Optical Breadboard Selection Guides

    The selection guides below list every size offered for our honeycomb, solid aluminum, and acrylic breadboards. Simply locate the specific width and length needed and then select the type of breadboard. Expand each table by clicking the More [+] button within the header.

    Thorlabs also offers several unique breadboard solutions. For applications requiring temperature control, we offer anodized aluminum water cooled breadboards in several sizes, in addition to a temperature-controlled mini-series breadboard for small-scale operations. Our anodized aluminum large-area translation stages and rotating breadboards offer hand-operated positioning control, while our manual and motorized translating mounting platforms are ideal for use in microscopy applications.
