Honeycomb core structure.
Maximum stiffness.
At the heart of the Optical Tabletop is a steel honeycomb core that does far more than hold the skins apart. It is the structure that gives the table its stiffness, its high natural frequency, its low compliance, and its fast settling behavior.
Ultra stiff by design. Ideal rigid body.
The honeycomb core forms a deep, lightweight sandwich structure with a very high stiffness to mass ratio. Cell geometry, core height, and skin thickness are tuned together so the tabletop resists bending across its entire span. That stiffness pushes the main resonant modes to higher frequencies, well above typical building vibration ranges. In real lab conditions, the table behaves much closer to an ideal rigid body instead of flexing with every disturbance.
It feels like a surface that stays composed, even when the environment is not.

High core density. Low dynamic deflection.
Low compliance comes directly from the honeycomb core structure: tall cells, high core density, and many closely spaced support points increase bending stiffness and reduce how much the top skin can flex between cells. As a result, dynamic deflection stays very low when the table is excited, the surface moves less under changing loads, long optical paths stay aligned, and the tabletop does not behave like a flexible plate during real experiments.
Internal damping. Controlled vibration.
The honeycomb core is bonded to the skins with adhesive layers that act as internal damping. When the tabletop vibrates, shear in these thin films and at each bonded interface converts vibration energy into heat instead of letting it ring. Inside the sidewalls, highly damped wood composite panels work as built in absorbers, so the frame does not behave like a ringing metal box.
Because the honeycomb sandwich contains many joints, interfaces, and adhesive layers, it offers far more paths for vibration energy to be dissipated than a solid metal or granite slab. In practice, that means lower resonance peaks, shorter ring down times, and a surface that stops moving sooner after a disturbance. The result is a tabletop that feels mechanically calm: you tap it or adjust a stage, the motion dies out quickly, and your optics can get back to work.

Bonded under controlled pressure
for structural accuracy
Flatness at this level starts deep inside the tabletop. A precision hydraulic press applies uniform, repeatable pressure during bonding, ensuring consistent adhesive layers and eliminating voids or tension points that could warp the top skin.Flatness at this level starts deep inside the tabletop.

High-density honeycomb core for consistent support
The tabletop uses a sufficiently dense honeycomb core to support the skin across its entire span. Too little core depth or inadequate cell density allows the skin to flex between cells, preventing the table from ever reaching optical-grade flatness. The chosen core geometry ensures minimal unsupported regions and distributes load evenly.The tabletop uses a sufficiently densehoneycomb core to support the skin

Precision mounting grid for precise alignment.
On top of this ultra flat surface sits a precision mounting grid. Each tapped hole is accurately machined and aligned so optics and instruments can be placed exactly where your design requires them, with repeatable positioning across the tabletop. You get cleaner layouts, easier alignment, and setups that can be disassembled and rebuilt with confidence.
Every hole, individually sealed.
Inside the tabletop, every mounting hole is closed off with an adhesive bonded cylindrical cap. Each hole receives its own cap so the threads are not an open path into the honeycomb core. The caps bond directly to the underside of the top skin and create a tight seal that blocks liquids, dust, and moisture from entering through the mounting pattern. Spilled solvents or cleaning fluids stay on the surface instead of seeping down into the structure.
By keeping the honeycomb core dry and clean, the sealed holes protect the adhesive bonds and internal damping layers, prevent corrosion and loss of stiffness inside the core, and help the tabletop maintain its vibration performance over many years. What you see on the outside is a simple, clean grid of mounting points. What you do not see is a forest of cylindrical caps working quietly underneath, protecting the core and preserving the way the table feels and performs from day one.
