An MB810U Breadboard Supported by BMF4 Mounting Feet that are Attached Using the Included Cap Screws

• Accepts 1/4"-20 (or M6) Socket Head Cap Screws (Included Only with BMF4)
• Helps Reduce Shock and Vibration
• Useful for Uneven Surfaces

The RDF1 Rubber Damping Feet are useful for stabilizing aluminum breadboards. Mount one foot under each corner of the breadboard to help reduce vibrations and to compensate for uneven work surfaces. The Ø1" feet help support heavy loads and accept either the imperial (1/4") or metric (M6) socket head cap screws found in our HW-KIT2 and HW-KIT2/M hardware kits, respectively.

The BMF4 Adjustable Breadboard Feet can be used to stabilize any of our aluminum or stainless steel breadboards. One foot is mounted under each corner to help reduce vibration. They provide ±0.120" (±3 mm) of vertical height adjustment to allow the breadboard to be leveled using a novel ±10° pivot design that compensates for uneven work surfaces. The BMF4 comes with 1/4"-20 socket head cap screws, while the BMF4/M comes with M6 socket head cap screws.

the SWB(/M) Base

• 0.66" Long, 1/4"-20 (M6) Threaded Mounting Stud
• CF125 or CF175 Clamping Fork (Sold Separately) Secures Base and Locks Swivel Joint 
• ±6° Swivel Compensates for Uneven Surfaces
• Locking Nut Included for Height Adjustments
• 1/8" (3 mm) Hex Socket on Bottom for Tightening
• Machined Bottom Relief Cut for Added Stability

Thorlabs' SWB(/M) Articulated Mounting Base can be used to stabilize and level a mounted component, such as a breadboard, or to correct for beam pointing errors. It features a 0.66" long, 1/4"-20 (M6) threaded mounting stud with ±6° of freedom in all directions to adjust for uneven work surfaces or compensate for angular misalignment. The base can be secured to an optical table or breadboard using a clamping fork, such as the CF125 or CF175, as shown in the photo to the right. Securing the base in place with a clamping fork will lock the articulated joint in position.

A Ø1" tapered locking nut is included for components requiring a larger support surface and provides 0.375" of vertical height adjustment. The tapered design prevents the locking nut from contacting a clamping fork when being secured in place. Additionally, torque holes that accept a 5/64" hex key are included in the lock nut and mounting stud to aid in securing a mounted component at a specific height. A 1/8" (3 mm) hex socket is also included on the bottom of the mounting base to actuate the threaded mounting stud.

Breadboard (MB8) with low-friction feet. KL01 kinematic stops preserve breadboard location.

• Low-Friction Delrin^®*
• Allow Breadboards to be Moved Easily
• 1/4"-20 or M6 Mounting Studs
• Helps Reduce Shock and Vibration

The DF1 Feet are useful for smaller aluminum breadboards in applications that require frequent repositioning. Made from low-friction Delrin, they allow the breadboard to slide easily without marking or scratching the work surface. Supplied as a set of three, the feet have a simple 1/4"-20 or M6 stud and are ideal for use with our range of kinematic breadboard stops.

The first photo to the right shows three KL01 Kinematic Stops being used to maintain the position of an MB8 Breadboard with DF1 Low-Friction Feet. To match the height of the breadboard and low-friction feet, each KL01 stop is mounted on a BA2S6 Spacer. Two KL01 stops are used to define a line on one edge of the breadboard, while the third acts as a stop for the perpendicular edge of the breadboard. Thus, the breadboard can be removed from its position and returned with good repeatability.

Four AV4 Feet Supporting an MB12 Breadboard

• Four Size Options Available for Benchtop Vibration Isolation
• Available Mounting Options:
  • 1/4"-20 (M6) Tapped to Directly Attach to a Breadboard
  • Adhesive Mounting Surface to Directly Attach to Untapped Surfaces
• Supplied as Set of Four
• Use Extra Feet to Increase Load Capacity

These Sorbothane mounting feet provide a passive isolation solution for workbench-mounted breadboards. They can also be used to isolate noisy equipment from the optical table or breadboard surface. Unlike our pneumatic benchtop isolation solutions, these solid Sorbothane feet do not require inflation.

The AV4(/M), AV5(/M), and AV6(/M) mounting feet each contain internal 1/4"-20 (M6) threading with four included 1/4"-20 (M6) threaded studs. In contrast, the AV3 mounting feet are not threaded, and are attached to equipment or breadboards using the included double-sided tape. See the table below for the load capacities and dimensions of each isolator. When choosing an isolator, we recommend picking the isolator that offers the largest range of damped frequencies for the specific load being used. For further assistance in choosing the proper Sorbothane isolator, please see the Feet Selection Guide tab above.

Please note that these feet may have silicon residue on their surface from the molding process. Thorlabs offers SB12E Adhesive Felt Sheets to reduce contact between this silicon residue and the work surface. These sheets can be cut to match the size of the sorbothane and easily attached via the adhesive side. The residue can also be removed by wiping the feet with an alcohol-based solvent such as isopropyl alcohol (IPA).

• Build Your Own Kinematic Base System with Our Breadboards
• Magnetically Coupled with High-Strength Rare-Earth Magnets
• Top and Bottom Plates Available Together or Separate
• Turn Any Breadboard into a Kinematic Base Using the 1/4"-20 (M6) Taps

The KBS98 kinematic seats can be used to convert any breadboard into a kinematic platform that can be removed and replaced with a high degree of accuracy. The KBS98 consists of six plates - three top plates and three bottom plates.

Each top plate has an inset ball that will sit in the V-groove of the bottom plate. The three top plates should be attached to the optical breadboard that is being taken out of and put back into an optical setup. The bottom plates have V-groove slots and should be mounted on the stationary optical table or breadboard. The plates should be arranged in a triangular pattern near the corners/edge of the optical breadboard with the V-grooves in the bottom plates aligned so that the three axes defined by the V-grooves intersect at a common point (refer to the photo above). Proper positioning of the plates is necessary in order to maximize the stability of the optical breadboard. If multiple breadboards are going to be substituted in and out of the same place, additional top (KBS98T) and bottom (KBS98B) plate sets are available below.
