Optical Breadboard Tabletop-class performance in a compact design.
The Optical Breadboard is designed for experiments where vibration control is critical but a full‑size
table is not practical. It provides a compact, low‑profile, ultra‑rigid platform for lasers, microscopes,interferometers, and other sensitive optical setups mounted on existing benches and frames.

See how it is built.

Honeycomb core structure.
Maximum stiffness.

At the heart of the Optical Breadboard is the same steel honeycomb core used in our full‑size tabletops. It does far more than separate the skins – it provides the stiffness, high natural frequency, low compliance, and fast settling behavior that make the breadboard a stable platform for demanding optical work in a compact design.

Ultra‑stiff by design. Rigid where it counts.
Our optical breadboards use a deep, lightweight sandwich construction to achieve an exceptional stiffness‑to‑mass ratio in a compact footprint. Core geometry, core height, and skin thickness are tuned as a single structure, so the breadboard resists bending across its entire working surface—even with concentrated loads from posts, stages, and mounted assemblies.
That high stiffness pushes the primary resonant modes to higher frequencies, above the range where typical building and bench vibrations carry the most energy. In real lab conditions, the breadboard behaves much closer to an ideal rigid body—supporting optics without the subtle flexing that can turn small disturbances into visible drift.
It feels like a surface that stays composed, even when the environment is not.
High core density
High core density. Low dynamic deflection.
The Optical Breadboard uses a high‑density honeycomb core to support the top skin across its entire area. In a compact platform, too little core depth or insufficient cell density would allow the skin to flex between cells, preventing the surface from ever achieving optical‑grade flatness. The carefully chosen core geometry minimizes unsupported regions and distributes loads evenly, maintaining a precise reference plane even on a small breadboard.

Internal damping. Controlled vibration.
In the Optical Breadboard, the honeycomb core is bonded to the skins with adhesive layers that also serve as internal damping. When the breadboard 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 act as built‑in absorbers, so the compact structure does not behave like a ringing metal box.
Because the honeycomb sandwich contains many joints, interfaces, and adhesive layers, the breadboard provides far more paths for vibration energy to be dissipated than a solid metal or granite plate. 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 breadboard that feels mechanically calm: you tap it or adjust a stage, the motion dies out quickly, and your optics can get back to work.

Ultra flat surface with
precision mounting grid.

Precision mounting grid

Surface flatness ±0.03 mm, engineered with intention

The Optical Tabletop is machined to a verified flatness of ±0.03 mm across the full working area.
It forms an optical reference plane that combines engineering precision with a premium, refined feel, supporting long-range alignment and high accuracy beam paths with confidence.

Bonded under controlled pressure for structural accuracy

Flatness at this level starts deep inside the breadboard. During bonding, a precision hydraulic press applies uniform, repeatable pressure across the honeycomb core, creating consistent adhesive layers and eliminating voids or tension points that could otherwise distort the top skin.

High-density honeycomb core for consistent support

The Optical Breadboard uses a high‑density honeycomb core to support the top skin across its entire area. In a compact platform, too little core depth or insufficient cell density would allow the skin to flex between cells, preventing the surface from ever achieving optical‑grade flatness. The carefully chosen core geometry minimizes unsupported regions and distributes loads evenly, maintaining a precise reference plane even on a small breadboard.
Precision mounting grid
Precision mounting grid for precise alignment.
On top of this ultra‑flat surface, the Optical Breadboard features 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 breadboard. The result is cleaner layouts, easier alignment, and compact setups that can be disassembled and rebuilt on the same platform with confidence.

Every hole, individually sealed.

Individually sealed mounting holes
Inside the Optical Breadboard, every mounting hole is closed off with an adhesively bonded cylindrical cap. Each hole has its own cap, so the threads are never an open path into the honeycomb core. The caps bond directly to the underside of the top skin, creating a tight seal that blocks liquids, dust, and moisture from entering through the mounting grid. Spilled solvents or cleaning fluids stay on the surface instead of seeping 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 breadboard maintain its vibration performance over many years. From the top you see only a simple, clean grid of mounting points. Hidden beneath is a dense array of cylindrical caps working quietly to protect the core and preserve the way the breadboard feels and performs from day one.
