The Surface Concept GmbH was founded in 2005 based on a spin-off from the Physics Institute at the University of Mainz. The company bundles strong skills of experienced physicists working on delay line detector developments for more than 12 years, on analytical electron microscopy for more than 15 years, and the key developers have about 20 years experience in the field of electron spectroscopy methods, particularly under ultra-high vacuum conditions. Today, Surface Concept designs, produces, and delivers between 20 and 30 highly sophisticated photon and particle detectors each year.


We are development partners of several research groups, affiliated to Universities, to the Max-Planck society, to the Helmholtz society, and to synchrotron facilities. Surface Concept is a member of the Network Of Competence, a cooperation of four manufacturers producing systems and components for surface science (Specs, Createc, Bestec and Surface Concept). We cooperate tightly with LaVision Biotec, mainly in the field of time-resolving photon detection, and with Focus GmbH for applications of time resolved electron detection in photoemission electron microscopy.
