RDF1 Application

BMF4 Application

• 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.

• 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.

• 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.

Four AV2/M Feet Supporting an MB2025/M Breadboard
(Parts Sold Individually)

• Ideal for Benchtop Vibration Isolation
• 1/4"-20 (M6) Threaded Stud Allows Fitting to Base of Test Equipment
• Load Capacity (Set of Four): 44 - 70.4 lb (20 - 32 kg)
• Use Extra Feet to Increase Load Capacity
• Supplied as a Set of Four

Thorlabs' Sorbothane Mounting Feet provide a passive isolation solution for workbench-mounted breadboards. They can also be used to isolate vibrationally noisy equipment from the optical table or breadboard surface. The feet do not require inflation, are supplied as a set of four, and have a 1/4"-20 (M6) thread for easy mounting.

The ideal load capacity per foot is 5 - 8 kg (11 - 17.6 lb). For heavier loads, simply add more feet. To achieve optimal isolation, use the feet as close to the maximum load as possible.

Note that these feet may have silicon residue on them from their molding process. To remove the residue, wipe the feet down with methylene chloride, taking the appropriate precautions.

• 12" x 12" Sheet Size with 1/4" or 1/8" Thickness
• Easy to Cut and Shape for Multiple Use
• Hardness: 70 Durometer
• Absorbs up to 95.5% of Impact Energy
• Can be Used as Vibration Isolation Material
• Ideal for Use with our Aluminum Breadboards

The pliable Sorbothane Sheets are ideal for isolating mechanical noise or vibrations. The substrate absorbs up to 95.5% of impact energy and then reforms to its original shape. The 1/8" or 1/4" thick sheets can be placed under a breadboard in single or stacked layers to counter the effects of uneven work surfaces or to isolate the breadboard from vibrations. For objects over 5 lbs, the 1/4" thick sheets (SB12B) are recommended. The Sorbothane sheet may be hand-cut, die-cut, or kiss-cut to suit various custom applications. Please contact Technical Support to request Sorbothane sheets with a lower Durometer.
