Thorlabs' Mini-Series breadboards, designed for setups where space is a premium, offer increased tapped hole density with 0.4" or 0.5" (10.0 mm or 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. Breadboards with 4-40 (M3) taps are compatible with smaller 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.

We also offer a selection of breadboards with 8-32 (M4) and 1/4"-20 (M6) mounting holes designed for use with Thorlabs' Customizable Electronics Enclosures or LCC7201C Birefringence Imaging System. These breadboards have counterbored mounting holes positioned to allow the breadboards to be mounted directly into the compatible system. The breadboards for the imaging systems also feature a Ø1.97" (Ø50.0 mm) central aperture aligned with the optical axis of the imaging system.

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 Sales.

Hey Thorlabs I am mounting components that use two M4 taps next to each other (in order to secure alignment). For this, a "pure M4 edition" of the "Breadboards with 8-32 (M4) and 1/4"-20 (M6) Taps" would offer greatly enhanced flexibility. That is, an edition where all M6 taps are replaced by M4 taps. Best regards Thomas

Response from Charles at Thorlabs: Thank you for your query. I can see how this could be helpful and it is something we can perhaps offer as a custom item. Since you opted not to be contacted, please contact your local technical support team if you would be interested in a quote.

Optical Breadboard Selection Guides

Table 10A and Table 10B 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 aluminum liquid-cooled breadboards and baseplates in several sizes, in addition to a temperature-controlled mini-series breadboard for small-scale applications. 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.

Breadboards for Electronics Enclosures, 8-32 (M4) and 1/4"-20 (M6) Taps

The MSB1823(/M) and MSBU1823(/M) breadboards are designed to fit inside the EC2030A(R) or EC2030B(R) benchtop enclosures for custom electronics, and the MSBU3038(/M) breadboard is designed to fit inside the EC2U and EC3U 19" rack enclosures for custom electronics.The MSB1823(/M) and MSBU1823(/M) have a thickness of 0.28" (7.0 mm) while the MSBU3038(/M) has a thickness of 0.37" (9.5 mm). In addition, these breadboards have four M3 counterbored mounting holes for compatibility with the enclosure, rather than 1/4" (M6) counterbored holes.
