Optical Tabletop
A foundation for unlimited discovery
Measured performance
Measured, not assumed
Every DVIO-B tabletop is built in our own factory and measured after it is built: compliance and natural frequency by impact test at four points on the finished surface, 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)
- 38 nm/N
- 1,800 × 1,200 × 300 mm · median of 7 production units
- First natural frequency
- 200 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.
- 154 tabletops and breadboards impact-tested, from 500 × 400 × 25 mm to 3,600 × 1,500 × 400 mm; across the whole range compliance follows the sandwich-plate law, which is direct evidence that each bonded structure behaves as one plate.
- 126 of the 154 units returned the same natural frequency at all four measurement points.
- Flatness is measured on every unit; the ±0.03 mm specification applies to the mean of eight zones, for every catalogue size.
