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. The holes are threaded completely through these breadboards, allowing components to be mounted on both sides at once. Breadboards are offered in either 1/2" or 3/4" thicknesses.

Each breadboard features four or five mounting holes that are offset from the array of 1/4"-20 (M6) threaded holes 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 boards 18" or wider, metric boards 450 mm or wider). 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 (see photo to the right). The mounting holes may be used to attach the breadboards to variety of surfaces and mounts, including optical tables, other breadboards, mounting posts, and brackets. Please see the Mounting Options tab for more details.

This finite element analysis simulation shows the vertical displacement of two breadboards with 120 N force applied at center. The 1/2"-thick breadboard on the left shows a maximum displacement of 0.047 mm, while the 3/4"-thick breadboard on the right shows only 0.014 mm. The 3/4"-thick breadboard's increased stiffness leads to lower board displacement.

Other Breadboard Options
For vacuum applications, we recommend using our selection of Unanodized Breadboards. 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 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. The same double-hole-density pattern is also available on our Circular Breadboards.

Custom Breadboards

For applications with limited space, Thorlabs offers Mini-Series Breadboards with 4-40 (M3) or both 8-32 (M4) and 1/4"-20 (M6) tapped holes. These breadboards feature an increased tapped hole density and thinner breadboard thickness.

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 fill out our custom breadboards form.

Vertical Arrangement

Thorlabs' aluminum breadboards can be mounted vertically (or perpendicular to a mounting surface) using a wide variety of 90 degree mounting plates. For tall arrangements, we recommend the setup shown to the left. Here, the MB12 breadboard is vertically oriented using two VB01 Vertical Brackets. For smaller arrangements, the AB90, AP90, or AP90L Right-Angle Brackets may be used.

Vibration Isolating Feet

Thorlabs' aluminum breadboards may be mounted on a set of vibration isolation feet. These Sorbothane Mounting Feet may be used to isolate a small breadboard from its mounting surface.

Not shown: Standard RDF1 Rubber Damping Feet may also be used where high vibrational damping is not necessary.

Elevated Arrangement with Adjustable Mounting Feet

A set of Ø1.5" Mounting Posts can be used to elevate an aluminum breadboard off of the work surface. At left, an MB1824 breadboard is shown with four P6 Mounting Posts. An adjustable, self-leveling BMF4 Mounting Foot is attached to each mounting post. The self-leveling mounting feet feature rubberized feet and screw thread height adjustment.

Not shown: DP14A Damped Posts are available in 14" lengths for vibration sensitive elevated mounting applications.

Fixed Elevated Arrangement with Pedestal-Style Feet

A more permanent Aluminum Breadboard mounting option, shown to the left, features pedestal-style Ø1.5" Mounting Posts clamped to an optic bench. The MB1824 Aluminum Breadboard to the left is elevated off the optic bench surface using a set of four P6 Mounting Posts, each with a PB4 Pedestal Base Adapter and PF175 Clamping Fork.

Not shown: Ø1.5" Translating Posts or Ø1.5" Damped Posts may also be used in lieu of the P6 Mounting Posts for applications requiring further height adjustment or reduced sensitivity to vibrations, respectively.

Breadboard Enclosure Systems

Enclosures may be added to Thorlabs' aluminum breadboards to house light and dust-sensitive equipment. Thorlabs offers a variety of plexiglass and standard darkening enclosures. The enclosure shown to the left has the front panel removed for access. Enclosures with sliding doors fabricated from plexiglass or black hardboard are also available.

Breadboard Mounting Brackets

The PSY321(/S) Post Mounted Breadboard Brackets are designed to securely mount breadboards onto Ø1.5" posts. Each bracket will support any aluminum breadboard up to 12" x 12" (300 mm x 300 mm) in size, and has a maximum load capacity of 20 kg (44 lbs).

Not shown: PSY360 and PSY361 Breadboard Mounting Brackets can be used to mount breadboards to the lean bars of a ScienceDesk™ workstation.

What temperature do these breadboards go up to? I would like to use one to support a vacuum chamber during a high temperature bake.

cwright (posted 2020-07-16 10:24:04.0)

Response from Charles at Thorlabs: Thank you for your query. We do not have a specified upper limit for these boards. Since aluminium oxide and aluminium have different thermal expansion coefficients it is possible, depending on the number of heating cycles, the temperature you are using and how quickly it is heated, that you could experience cracking of the coating. I would recommend using our unanodised breadboards for such an application.

CC Kwong (posted 2020-05-17 23:45:49.9)

May I know what is the type of anodization that is applied to the breadboards? Thank you.

DJayasuriya (posted 2020-05-18 09:35:32.0)

Thank you for your inquiry. It's sulphuric acid anodising that we use with our breadboards.

What grade of aluminum is the board made from? For example 70/75 T6? 60/65, etc. I did not find it in the specs cited. Thanks very much.

DJayasuriya (posted 2020-05-07 07:20:14.0)

Thank you for your inquiry. For solid aluminium breadboard we use 5083 Aluminium Alloy.

Fedor Talantov (posted 2020-04-27 22:19:02.29)

Hello, It appears that the solidmodels for the 0.75" thick breadboard (as well as some of the metric breadboards) have an issue with downloading, and do not import correctly. Specifically, the downloaded file is is ~24kB, as compared to 1953kB for the MB1830 solidmodel. Thanks, Fedor.

Could you please tell me what is the pitch of the threading in the M6 holes of the aluminium breadboards? Is it e.g. fine 0.75 mm or coarse 1 mm?

YLohia (posted 2019-12-12 04:24:46.0)

Hello, the pitch on the threaded M6 holes is M6 X 1.0.

What is the flatness tolerance on the face of your solid breadboards? E.g. MB4560/M Thank you

bwood (posted 2018-03-02 05:57:28.0)

Response from Ben at Thorlabs: Thank you for your question. The flatness tolerance of the top face of our aluminium breadboards is ±0.15 mm over 0.09 m².

When using the breadboard in the vertical arrangement, what is the maximum weight that can be mounted?

bhallewell (posted 2016-03-03 11:39:00.0)

Response from Ben at Thorlabs: Thank you for your feedback. We will contact you directly to discuss the load characteristics of the vertically orientated breadboard as the recommended load would be dependent upon a number of factors e.g. stability based on the size of the board used & whether the length or height is aligned parallel to the mounting surface, vertical position of the load, the height/moment of the load etc. I will contact you directly to obtain some details and work this through with you.

What is the hole location tolerance for the 1/4-20s and the counterbored holes??? from the edge and between holes.

besembeson (posted 2016-01-19 01:23:17.0)

Response from Bweh at Thorlabs USA: The tolerance is +/-0.25mm.

bhallewell (posted 2016-01-21 04:08:28.0)

Response from Ben at Thorlabs: The following are referenced from hole centres. Counterbore-Edge Distance - 25.4mm ± 0.25mm Mounting Hole-Edge Distance - 12.7mm ± 0.25mm Hole-hole Distance - 25.4mm ± 0.25mm I hope this is of use to you.

cddarne (posted 2015-09-03 17:26:03.24)

I wanted to know the maximum weight bearing capacity for the breadboards. I need to make up my mind based on this criterion. Is this information included in the product information?

msoulby (posted 2015-09-07 09:19:23.0)

Response from Mike at Thorlabs: The MB breadboards are made from a solid piece of aluminium tooling plate which is 12.7mm thick. We do not have and load capacity data for this as it is simply a solid piece of metal. However if you are using a larger sized breadboard then the amount of deflection due to load on the breadboard will be higher. If you intended to us a large breadboard with a large amount of weight then we would recommend using our thicker Nexus honeycomb breadboards instead http://www.thorlabs.de/navigation.cfm?guide_id=44 or even an optical table http://www.thorlabs.de/navigation.cfm?guide_id=41

elkeneu (posted 2015-04-27 16:21:55.847)

for stray light sensitive applications it would be useful to have breadboars where the M6 threaded holes do not go all the way through the breadboard.

msoulby (posted 2015-04-28 07:03:29.0)

Response from Mike at Thorlabs: We have custom breadboard capabilities and have contacted you directly to get more information about the breadboard that you require.

tcohen (posted 2012-06-25 08:59:00.0)

Response from Tim at Thorlabs: Thank you for your feedback! The current design has the mounting holes for the breadboard counterbored and offset which allows the full surface of the table to be used for mounting components. We would like to discuss the details and benefits of your proposed design with you, but we do not have your email. Please email us at techsupport@thorlabs.com to further discuss your design.

user (posted 2012-06-18 10:25:09.0)

Opposite mount hole spacing to the hole pattern would be useful. As would having the mount holes counterbored so that the corner three holes in the breadboard can be used.

bdada (posted 2011-09-20 17:34:00.0)

Response from Buki at Thorlabs: Thank you for your feedback. The MB series breadboards are made from solid aluminum so they are non-magnetic. We will clarify this on our website.

mabdelrahman (posted 2011-09-14 08:58:35.0)

Are these breadboards magnetized? It may be useful to add this to the item description. Mohamed Ramy

Response from Tor at Thorlabs to bezdecny: Thank you for your suggestion. We are using it to help determine whether this should be added as a stock item. In the meantime, I will contact you for more details to see whether we can provide this to you as a custom item.

bezdecny (posted 2010-12-07 11:08:17.0)

It would be very useful if you had an option to purchase breadboards with opposite mounting hole spacing to hole pattern. For example a 300mm x 300mm board with M6 thread, but with mounting holes 10" apart.
