F-CLUE Compact Hyperspectral Cathodoluminescence

Compact Hyperspectral Cathodoluminescence

The F-CLUE is the optical fiber coupled solution offering a flexible interface for Cathodoluminescence Imaging and Spectroscopy analysis.

Thanks to its rugged ultra-compact footprint and deported spectroscopy modules, it can be installed even on very busy microscopes and/or in harsh industrial environments or extreme conditions (clean room, mobile laboratories…).

Like the whole CLUE series, its compact and fully retractable collection interface offers the possibility to upgrade CL on any commercial microscope without any restriction on performance.

The accurate video assisted micropositioning of the mirror permits to optimize collection efficiency and guarantee the best performance and reproducibility of your CL measurement.

Controlled by Labspec 6 Simply Powerful software suite, F-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…)

Flexible solution to fit any kind of environment, featuring:

•     Imaging and/or hyperspectral CL
•     Rugged optical fiber interface
•     Selection of ellipsoidal or parabolic retractable mirror to fit all sample types and applications
•     Powered by LabSpec 6TM Software
•    Fully motorized spectrometer
•    Optional RGB filters

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.
Hyperspectral 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…).
