H-CLUE Hyperspectral Cathodoluminescence

The H-CLUE direct coupled solution offers the ultimate performance for Cathodoluminescence Imaging and Spectroscopy analysis.

Embedding field-proven optical components of HORIBA Scientific, H-CLUE overcomes its competition in terms of sensitivity over wide spectral ranges from FUV to extended NIR.

Modularity and versatility are highlighted by the game-changing OptiLink module placed between the retractable mirror interface and the spectrometer and offering any other possibility of CL imaging such like polarized CL, RGB CL, Angular Resolved CL (AR-CL) and Time Resolved CL (TR-CL).

Controlled by Labspec 6 Simply Powerful software suite, H-CLUE features advanced unique functionalities for both fast imaging and spectroscopy analysis (KIA spectral database, SWIFT, cosmic ray removal, peak fitting, particle finder, mosaic, multivariate analysis, advanced 3D display…)

Free space optical coupling for the highest performance over the widest CL spectral range

  • Fully automated control
  • Motorized RPM with fine adjustment

Add Cathodoluminescence and Raman Capabilities to your Electron Microscope

CathodoLuminescence (CL) is a non-destructive technique providing maps of optical and electronic properties of many kinds of materials with a nanometric spatial resolution.
Cathodoluminescence is similar to Photoluminescence (PL) technique, but the excitation by high energy electron beam can produce all the transitions to the higher energy excitation states and induce light emission from DUV to NIR.
CL technique is particularly suitable for analysis of particles, group IV semiconductors, thin films and nanostructures, novel photonics materials, oxides and minerals.

Raman spectroscopy is based upon the interaction of monochromatic light such like a laser with the molecules within a material.
This technique typically provides information about chemical structure, phase and polymorphy,  crystallinity, and molecular orientation.
Raman analysis can be applied to any kind of organic (biological, polymers…) and inorganic  (minerals, semiconductors, glasses, oxides…) materials, except pure metals.

Gain unique insight into the chemical and electronic properties of materials with nanoscale resolution!

Measuring CL and Raman / PL photons inside the electron microscope* specimen chamber, in a SameSpotTM configuration, permits to measure the following parameters in the same conditions of
pressure and temperature as other EM measurements (EDX, XRF, EBSD, Auger…).

• Electrical and compositional properties
• Quality control and failure analysis
• Defects, impurities, dopants, vacancies
• Contaminations and inclusions
• Zoning analysis in zircons
