Thorlabs' Mini-Series breadboards, designed for setups where space is a premium, offer increased tapped hole density with 1/2" (12.5 mm) spacing. These high-density breadboards are offered with either 4-40 (M3) tapped holes or both 8-32 (M4) and 1/4"-20 (M6) tapped holes.
Our Mini-Series line consists of components that are compatible with 4-40 (M3) or 8-32 (M4) threads. The 4-40 (M3) taps in the MS12B(/M) breadboard make it compatible with smaller 4-40 (M3) Mini-Series components, such as our Ø6 mm posts. Our other breadboards are compatible with 8-32 (M4) Mini-Series components, such as our Ø12 mm pedestal posts and MSL post holders, and also include 1/4"-20 (M6) taps for integrating larger optomechanical components, such as our Ø1/2”, Ø1”, and Ø1.5” post assemblies.
Each breadboard features two, four, or five counterbored mounting holes, depending on the size of the board, enabling these breadboards to be mounted onto our standard breadboards, mounting feet, or post assemblies. For breadboards that have a fifth counterbored hole, it is located at the center of the breadboard to reduce stress at the four corners and to increase system rigidity when mounted. Refer to the tables below for more specifications.
Two imperial and two metric breadboards with both 8-32 (M4) and 1/4"-20 (M6) tapped holes, featured below, are designed for use with the EC2030A and EC2030B customizable electronics enclosures. 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. Anodized and unanodized versions are available.
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 use our contact Tech Support.

The MSB1823(/M) and MSBU1823(/M) breadboards are designed to fit inside the EC2030A(R) or EC2030B(R) benchtop enclosures for custom electronics. The breadboards have a thickness of 7.0 mm, which is thinner than the standard aluminum breadboards sold above. In addition, these breadboards have four M3 counterbored mounting holes for compatibility with the enclosure, rather than four 1/4" (M6) counterbored holes. See the table to the right for specifications, and see the PDF drawings for details by clicking on the red Docs icons (
