Measuring and Testing procedure
Devices and processes developed and built by ZEA-1 are often one-offs, at the limits of what is feasible or we push these limits. This places special demands on measuring and testing technology, both in development and for quality assurance. With scientific precision instruments, "precise" is often not precise enough. This is the case with components that have to be leak-proof, or precision devices that have to be manufactured and positioned exactly to a thousandth of a millimeter. To ensure that nothing drips, leaks, is uneven or gives way under load, every important component, every instrument and every system is tested with the utmost care. If the commercially available test methods reach their limits, we develop new methods that meet the high demands of research.
In particular, surfaces such as ceramics for fuel cells or joining and fitting surfaces must be very planar or even reflective. We measure roughness and flatness without contact, for example using a confocal white light sensor in combination with a spectrometer, with an accuracy of up to 50 nanometers - which corresponds to 0.00005 millimeters.
