Cathodoluminescence System HCLUE

The optimal CL package for academic research.

  • customized setup;
  • high sensitivity;
  • enhanced spectral range.

HCLUE, with its mirror-based couple, is the optimal CL package for academic research, combining the modularity of our spectrometers with the high sensitivity of our wide range of detectors. HCLUE is the perfect tool to analyze very weak CL signals, keeping optimum performance over a wide spectral range.

HCLUE system provides high resolution spectral information with the spatial resolution of an electron probe. We feature the widest spectral range available (UV-VIS to IR), fast CL imaging, CL spectroscopy for detecting trace elements in natural and synthetic minerals, and hyperspectral mapping.

HCLUE system can integrate HORIBA's MicroHR and iHR spectrometers, Synapse CCDs, and photomultiplier tube detectors to create a range of CL solutions. HCLUE is also fully automated, controlled by our LabSpec software for setting of hardware experimental parameters, data-fitting, display and export. It is easy to use and offers comprehensive system control, and advanced data acquisition routines.
