What can be measured with CONSIGNO measuring devices?
Almost all components and surfaces can be measured with CONSIGNO measuring devices. Neither color, structure nor transparency have any influence on the measuring principle. Both transparent objects such as glass and highly absorbent objects can be measured. A rough surface can be measured just as reliably as a reflective object.
How long does a measurement take?
How long a measurement takes depends heavily on the application. A simple roughness measurement with a measuring field takes approx. 2-3 seconds. If stitching is necessary so that the correct measuring length can be recorded, this can take up to 20 seconds for a length of 4 mm.
In general, it can be said that a measurement takes longer the higher the accuracy requirements are. A measurement over a large height range, for example for a step measurement, also takes a little longer than on a flat surface.
How does confocal microscopy work?
The confocal measuring principle is a proven measuring method. It is based on the fact that, thanks to a special optical structure, an object only becomes visible when it is in the focal plane of the measuring system. This means that only then is a bright and sharp image created. During a height scan, the brightness curve is recorded and the height of the brightest point is determined for each camera pixel. The surface is then located at this point.

Which software is used to operate the measuring device?
The measuring devices are operated using the open source software itom, a universally applicable framework for the control and laboratory automation of cameras and optical measuring devices. A simple graphical user interface was created by Optische Messtechnik to enable fast operation with minimal training requirements. The great advantage of the open source solution is that the software is freely available. This means that measurement data can be recorded at the measuring station. Evaluation and logging can be carried out with saved measurement data on any workstation computer. The integrated Python IDE also offers additional options for script-based control of the measuring device, particularly in the research and development sector.
What options are there for evaluating the measurement data?
The measurement data can be evaluated using the itom device software. Many parameters and evaluations are already included here, especially for roughness measurements. It is also possible to carry out further evaluation of the measurement data using MountainsMaps. A direct interface allows the measurement data to be easily exported to the comprehensive MoutainsMaps software solution.
Can you really measure everywhere with the mobile measuring device?
Yes and no. In principle, the measurements can be carried out in all areas and under all conditions. Depending on the application, the hardware interface or the holder can be adapted to the respective conditions. However, there are a few restrictions for applications in clean rooms, as the mechanical axes and guides can separate particles.
Are the measurement results also reliable in a production environment?
When measuring in a production environment, reliability is highly dependent on the accuracy requirements. For most applications, good results can still be achieved under conditions in a production environment. However, if the highest accuracies in the nanometer range must be achieved, a suitable environment is recommended.
Are the measurement results really reliable?
Yes, the measuring devices are calibrated and the reliability is validated using DakkS-calibrated standards. For example, calibrated roughness and step standards from Halle are used to verify the traceable calibration of the measuring devices.
What does the name Optische Messtechnik stand for?
A Optische Messtechnik stands for an Anglo-American unit of measurement. The abbreviation stands for "twentieth of an inch point". This means that 1 Optische Messtechnik corresponds to a length of approx. 17.6 micrometers.
