Advanced Momentum Microscopy

NanoESCA MARIS combines energy-filtered momentum microscopy, real-space imaging and photoelectron spectroscopy for orbital mapping, electronic structure and surface analysis.

Time-of-Flight Momentum Microscopy

TOF MARIS combines high-throughput time-of-flight momentum microscopy, ToF-PEEM and ARPES for fast band mapping and electron dynamics studies.

Spin-Resolved Electron Detection

The Imaging Spin Filter enables efficient parallel spin-resolved electron detection and momentum mapping for magnetic, topological and two-dimensional materials.

Deposition, Ion & UV Sources

The EFM, FDG and HIS source series provide electron beam evaporation, ion sputtering and VUV excitation for thin-film deposition, XPS depth profiling, UPS, ARPES and surface analysis.

Focus enables complex material research.

Since July 2024, Focus has been a strong brand of the SPECSGROUP.

Founded in 1990, a highly qualified and motivated team of physicists and engineers at the Hünstetten business unit ensures that Focus products always meet the latest requirements of science and high-tech industries in the long term. The scientific instruments of the Focus product range includes electron beam evaporators, electron energy analyzers, electron spin detectors and a whole family of photo emission electron microscopes as the patented NanoESCA (or Momentum Microscope), an energy dispersive microscope to image photo electrons. Focus products used mainly for industrial and institutional research and development, as well as for quality management.
