Optimized Damping

Broadband Damping
The most important feature of an optical table or breadboard is its resonant frequency. Since resonant frequency and vibration amplitude are inversely related, the resonant frequency should be as high as possible to minimize vibration intensity. Nexus tables and breadboards are broadband damped over a specific range of frequencies. For improved performance, the damping is optimized for each size of table and breadboard offered.

We have performed extensive testing to optimize the thickness/size ratio of our breadboards. Larger sized breadboards over 5' (1.2 m) long are offered with a standard 110 mm thickness. Smaller sizes are available in both 2.4" (60 mm) and 4.3" (110 mm) thicknesses.

Compliance

The most widely used transfer function for the vibrational response of an optical table is compliance. In the case of a constant (static) force, compliance is defined as the ratio of the linear or angular displacement to the magnitude of the applied force. In the case of a dynamically varying force (vibration), compliance is defined as the ratio of the excited vibrational amplitude (angular or linear displacement) to the amplitude of the force causing the vibration. Any deflection of the tabletop is evident by the change in relative position of the components mounted on the table surface. Therefore, by definition, the lower the compliance value is, the closer the optical table is to meeting the primary goal of optical table design: minimized deflection. Compliance is frequency dependant and is measured in units of displacement per unit force (meters per newton).

Figure 131A Compliance Test Schematic

See the Vibration Isolation Tutorial for more information on compliance.

Compliance Measurement Procedure
An impulse hammer is used to apply a measured force to the top surface of the table or breadboard, and transducers attached to the surface detect the resultant vibrations (see Figure 131A). The signals from the transducers are interpreted by the analyzer and used to produce a frequency response spectrum (i.e., a compliance curve). During the development phase of an optical table, compliance curves are recorded at many points on the tabletop; however, the compliance is always greatest at the corners. The compliance curves and data published by Thorlabs are taken with the sensor located approximately 6" (150 mm) from the corner of the tabletop (closer to the edge for small breadboards), with the point of impact just inboard of the sensor. This test location represents the worst case data.

Our team has over 25 years of experience designing optical tables, breadboards, and related accessories. We leverage this experience to ensure that our Nexus^® honeycomb optical tables and breadboards always meet two basic design goals: the natural resonances of the table should be as high as possible (well above the frequency of ambient environmental vibrations) and the table should be well damped (to quickly damp vibrations caused by equipment on the surface). To meet these goals, our engineers use a variety of tools to refine their designs, such as finite element analysis (FEA) and SolidWorks. FEA allows our engineers to evaluate various materials and to identify possible unwanted material stresses. SolidWorks is employed to build 3D models of every design.

Figure 27B Honeycomb Core of a Nexus Table During Manufacturing

Every Nexus optical table and breadboard is designed to be isotropic and symetrical in X, Y, and Z. For optimal thermal stability, only steel components are used in construction; no wood or plastic is used. Each table includes precision machined top and bottom mounting skins, an uninterrupted honeycomb core, and four side panels with finishing trim. See Video 27A for a simplified illustration of how our tables are assembled. For more details on each step in the process, read this tab.

Precision Steel Construction for Thermal Stability

Thorlabs' Nexus tables and breadboards feature all-steel construction, including 5 mm thick top and bottom skins and a 0.26 mm thick precision formed and welded steel honeycomb core. The core is geometrically formed using accurate pressing tools, and geometric pitch is retained by using welded flat shims. The honeycomb core in our Nexus tables and breadboards extends from the top skin to the bottom skin without intermediate layers, leading to a stiffer, more thermally stable product.

The key aspect of the thermally stable Nexus design is symmetrical isotropic steel construction in all axes. Steel components expand and contract similarly, maintaining flatness during changes in temperature. The steel core extends from top to bottom skin without intermediate plastic or aluminum spill management structures that reduce the overall stiffness of the product and introduce a higher coefficient of thermal expansion. Steel side panels are used rather than wood, which can introduce environmental instability due to susceptibility to moisture.

Machined Finish with Minimized Contamination Packaging

Automated Finishing Process
Our Nexus tables and breadboards feature an automated orbital machined matte finish that is significantly smoother and flatter than our previous product line. The improved surface finish achieves ±0.1 mm (±0.004") flatness over any 600 mm x 600 mm area. Large radius corners are incorporated into the design, resulting in less pointed edges for lab safety.

Click to Enlarge
Figure 27E Diagram showing the location of the honeycomb core and side panels, which do not intersect with any screw holes.

Sealed Edges with Anti-Static Packaging
All optical tables ship with a heat-shrink film that protects the table from most contaminants, such as dust, from entering the product during shipment. For additional protection, we offer an optional finishing and packaging service that is suitable for customers that want to minimize the presence of airborne contaminants on the interior and exterior surfaces of the table or breadboard. This includes anti-static packaging, which has a metallic foil inner layer protected by a heat shrink film outer cover, and gap-free edge panel construction to reduce static charge and prevent dust from entering the product.

Mounting Hole Options and Pattern

Individually Tapped, Countersunk Mounting Holes
Prior to bonding the components of the table, each mounting hole in the top surface is tapped and slightly countersunk to ensure that components mounted to the table sit flat. The mounting holes are then cleaned and sealed on the bottom with vinyl film discs (non-sealed models) or sealing cups (sealed hole models, see the Sealed Mounting Holes section). The vinyl film is easily punctured when using a hole for the first time. Cap screws can be finger tightened into the mounting holes of all Nexus tables and breadboards.

Reduced Hole Pattern Border
Our top surface hole patterns extend to the edge of the table or breadboard with only a 12.5 mm (0.5”) border, equal to half of a hole-to-hole spacing. This increases the usable area of the table and improves mounting option flexibility.

Figure 27F Nylon Sealing Cups Installation During Manufacturing

Increased Screw Depth and Optional Sealed Holes
Our custom-designed core maker produces precision formed and welded honeycomb core strips. The core is shaped and installed so that it does not intersect with any screw holes (see Figure 27E), allowing screws to be inserted far into the table, all the way to the bottom skin (for non-sealed-hole models). See the Specs tab for specific screw depth specifications, including outer border holes.

Sealed Mounting Holes
Tables and breadboards can be manufactured with nylon sealing cups glued to the underside of the top skin (see Figure 27F) for liquid spill management. Sealed hole tables are available in all sizes and thicknesses, and the maximum screw depth is 1" (25.4 mm).

Mounting Holes on the Bottom Skin
Our breadboards feature at least four mounting holes in the base skin, permitting the secure attachment of standard or vibration isolating feet and allowing more flexibility for integrating breadboards onto tables or into setups in addition to using breadboard stands.

Team, I'm looking at using these frames for one of my projects. I have a question. For the breadboard B2436F, do we have any specs on the compressive/crush strength? or the maximum load capacity it can withstand? Looking forward to your reply. Thanks.

do'neill (posted 2023-11-30 05:03:37.0)

Response from Daniel at Thorlabs. Due to the fact that the limiting factor in these cases is usually the frame, legs, etc that the breadboard is mounted on, we do not have a load capacity. I will reach out to you directly to discuss your application and see if there is anything I can suggest on this.

Hello， I can't find the load information in the specification, how much load it can support ? Thanks

cdolbashian (posted 2021-06-25 10:34:06.0)

These tables themselves can support a very large load breaking, and as that is the case, it is quite dangerous for us to test this for an absolute load spec. When considering the consequences of a large load on your table, the correct positioning of the supports is of the utmost importance. I have contacted you directly to further discuss your application and queries.

Miklos Kedves (posted 2020-06-24 10:12:54.25)

Dear Thorlabs, We need breadboards in order to extend the surface of the optical table next to a vacuum chamber. That is, these breadboards will be fixed to an optical table and about half of the surface will lie on the table and the other half will stretch out in the air. We are considering the model B3060A but I would like to ask which type of breadboard is more suitable for this purpose, the honeycomb structure or the aluminum plate? And what kind of fixing elements do you recommend to mount the breadboard on the optical table? Thanks

Sehr geehrte Damen und Herren, ich habe ein Frage zu Ihren Breadboards im Vergleich zu Aluminiumplatten mit den M6 Bohrungen. Gibt es einen deutlichen Unterschied der Breadboards hinsichtlich der Temperaturausdehnung im Vergleich zu Aluminium Vollmaterial? Wir benötigen ein Breadboard für Driftmessungen, wobei die Platte unempfindlich gegenüber Temperaturänderungen sein muss. Viele Dank und freundliche Grüße Fabian Suttner

cwright (posted 2020-03-06 08:04:15.0)

Response from Charles at Thorlabs: Thank you for your query. I understand you need a breadboard for drift measurements and that the board has to be insensitive to temperature changes. Subsequently you are looking to compare the thermal expansion properties of our honeycomb breadboards and our solid aluminium breadboards. Unfortunately we do not have such data for our honeycomb breadboard assemblies but I can tell you that the aluminium we use for our MB breadboards has a thermal expansion of 23.3 µm per Kelvin. While our passivated stainless steel breadboards will likely have the least thermal expansion out of those products in our catalogue, we would suggest that if your application requires extremely little to no thermal expansion that you look for an Invar breadboard. A member of our European tech support team will reach out to you for further discussion.

Would placing one of these breadboards directly on a active vibration-isolated tabletop compromise its damping performance?

Hello, thank you for contacting Thorlabs. These breadboards are commonly used with rigid, passive, or active isolating supports, so I would not foresee any problems.

Hi, What is the frequency range of the damping on the various Nexus breadboards?

tfrisch (posted 2017-01-25 04:04:36.0)

Hello, thank you for contacting Thorlabs. Typical compliance curves can be found at the link below. You can reach us at TechSupport@Thorlabs.com for more details. https://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=7154&tabname=Vibration%20Isolation

Is there any compliance data on vibration frequencies below 10 Hz, specifically down to 0.1 Hz?

How repeatable are the tables? Can I reliably duplicate mechanical setups within .5mm maybe even tighter tolerance? Edge, hole spread, any deviation?

Response from Ben at Thorlabs: Thank you for your question. The top surface of our Nexus breadboard range have hole location tolerances of +/- 0.2mm, i.e from the edge of the top surface, the hole centre will be located between 12.3mm & 12.7mm. Apart from our rigid rail systems, the majority of our post-mounted solutions do not precisely align to the hole matrix, as flexibility to fine-tune component position is required by many when locating parts on the table. Perhaps if you are seeking tighter tolerances, a custom platform solution would be an option to consider.

Hi, Can you give any more information on the density of the different types of breadboard (Nexus vs Intrinsically damped vs aluminium honeycomb). i.e. I would like to compare the mass of the different breadboards but I think the mass is only stated for the aluminium honeycomb breadboards. Thanks!

Response from Jeremy at Thorlabs: The weight of each breadboard (packed and unpacked weight) can be found under the "Specs" tab.

Hi, I was wondering is the breadboard B4560A is magnetic? Thanks! Best wishes Wiebke Knoll

msoulby (posted 2014-04-24 10:19:41.0)

Response from Mike at Thorlabs: The B4560A breadboard contains ferromagnetic steel in most of its construction. We do have a range of breadboards made from non-magnetic 304L steel http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=1084 or our ultra-light aluminium breadboards http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=1877 if you are looking for a non-magnetic option.
