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.

• Solid aluminum breadboards are offered with four different thicknesses: 0.5" (item # prefix MB), 0.75" (item # prefix MBH), 3/8" (item # prefix MS), or 0.28" (item # prefix MS). Select sizes are also available without an anodized coating (item #s ending with U).

• T, L, U, or N: Sealed Mounting Holes
• FN or AN: Nonmagnetic Mounting Holes
• Y or Z: No Mounting Holes
• S: Stainless Steel
• Tapped Hole Pattern Aligned at 45°
• Build-to-Order
• Includes a T-Slot in Side Panels for Compatibility with 25 mm Rail Accessories
• This product has an access aperture.
