Spectrium is a control and data acquisition software dedicated to EA15 class analysers. Spectrium, based on the latest developments in techniques and signal processing, is a progressive and optimised software tool for data acquisition and analytical instruments controlling, with very intuitive graphical interface.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.


Spectrium offers the possibility to define single independent regions as well as group them in sequences. Also, nesting sequences in major sequences are supported. Measurements can be done in Fixed and Scan modes and in both cases while processing, measurement tools, and FWHM display are available. In addition, not only a real-time view of the detector image in 3D as well as an energy graph but also a graph of the 2D detector image and the possibility to filter a chosen intensity range are at the user’s disposal.

The intensity graph is shown along the geometry axis. In order to guarantee compatibility with existing software, data export to TXT, HDF5, and CasaXPS is available by default.
