A Fifth Mounting Hole in the Middle of the Breadboard Increases Rigidity and Reduces Stress When Mounting Heavy Loads

Features

  • Large Range of Sizes Available from Stock
  • Standard Imperial and Metric Breadboard Hole Patterns
  • Offset Mounting Counterbores Allow a Full, Uninterrupted, Threaded Hole Matrix
  • Larger Breadboards Have a Fifth Center-Located Counterbore
    • Imperial: At Least 18" Wide
    • Metric: At Least 450 mm Wide
  • Black Anodized Surface with Low Reflectance
  • Double-Hole Density Versions and Custom Sizes Available

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.

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). 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 optical tables, other breadboards, mounting posts, brackets, or a variety of other surfaces or mounts. Please see the Mounting Options tab for more details.

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

Other Breadboard Options
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 SlimLine 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.

For limited space applications, Thorlabs offers the MS12B and MS12B/M Mini-Series Breadboards. These breadboards feature increased tapped hole density and thinner breadboard thickness.

MOUNTING OPTIONS

Vertical Arrangement

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.


Rubber Damping Feet

Vibration Isolating Feet

Thorlabs' aluminum breadboards may be mounted on a set of AV2 Vibration Isolating Feet, rated for 32 kg (70.4 lbs). These sorbothane bumpers 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.


Adjustable Feet Mounts

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.


1.5" Post Mounting

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.


Enclosure

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 XE25C5 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.
