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.

Measured performance
Measured, not assumed
A breadboard is the thinnest structure we build, so it is the one where the bond between skin and core shows first. Every DVIO-B breadboard is measured the same way as a full tabletop: an impact test at four points on the finished surface, and flatness on eight zones of the working surface. The figures below are medians of production units, stated with the size they were measured on.
- Compliance (peak of the frequency response)
- 406 nm/N
- 1,200 × 900 × 100 mm · median of 6 production units
- First natural frequency
- 250 Hz
- Same size
- Median flatness
- 15 µm
- 600 standard-size units measured since March 2025, every one within the ±0.03 mm specification
Compliance and natural frequency change with size and thickness. Ask for the measured record for the size you are considering.
- 77 breadboards impact-tested at 25, 50 and 100 mm; at 1,200 × 900 mm, going from 50 to 100 mm cuts compliance to a third (1,268 to 406 nm/N) and raises the first mode from 157 to 250 Hz.
- 65 of the 77 boards returned the same natural frequency at all four measurement points, and 73 agreed within 1.5 Hz — the honeycomb core is bonded across the whole surface.
- Flatness is measured on every unit; the ±0.03 mm specification applies to the mean of eight zones, for every catalogue size.
