Add CLUE to your SEM Designed for your SEM and application The CLUE family offers dedicated CL systems for imaging and spectroscopic analysis suitable for most SEMs. In addition, when combined with other techniques such as EBIC or EDS, CLUE adds enhanced analytical capabilities to SEMs, by keeping the sample in the same spot while performing these techniques. The modular and flexible design of the CLUE systems provides optimal CL performance for a wide range of applications, with each component configured to satisfy most rigorous experimental requirements. It also makes upgrading the system easy by adding components to the existing CL-collecting interface. Maintains original SEM functionality In a CL experiment, the specimen is excited by an energetic electron beam from the SEM. The emitted light is collected by a parabolic mirror installed under the electron beam. The original functionality of the SEM is maintained, for the mirror is fully retractable. High-efficiency CL signal-collection The customized CL-collecting system uses a diamond-turned parabolic mirror designed with optimal optical properties, e.g., wide solid angle of collection for maximum photon-capture and specific optical coatings to enhance the efficiency at your working wavelengths. The mechanical interface is adapted for large-specimen chambers, and is fully adjustable and retractable under vacuum. Please check with your local representative for compatibility with your SEM. Flexible spectral CL analysis By separating the spectroscopic systems and CLcollector section, the CLUE series provides high flexibility, ensuring compatibility with various types of SEMs. In an environment of limited size, the spectrometer is coupled to the collecting optics via a fiber-optic cable. For extended capabilities, a mirror-based coupling is available, perfect for multi-spectrometer and/or multi-detector systems, thereby optimizing the efficiency over the various spectral regions of interest.

Enhance your Scanning Electron Microscope Capabilities Take a step further with cathodoluminescence techniques Cathodoluminescence (CL) is an essential non-destructive analytical technique useful in a wide range of applications including semiconductors, optoelectronics, dielectrics and ceramics. CL is also a powerful tool for investigations in geology, mineralogy, forensics, and life sciences. In combination with electron microscopy, CL offers high spatial resolution combined with high spectral resolution and correlation with surface morphology. CL is a unique materials-characterization...

Cathodoluminescence Spectroscopy and Imaging Analysis Add structural identification to microscope images Principle Light emitted from a specimen in response to electron-beam irradiation, cathodoluminescence (CL), is collected by the optical interface and analyzed spectroscopically, providing detailed characterization of the physical properties of the sample. Backscattered Electrons Xray Secondary Electrons Traps Traps Electron Beam When excitation energy returns to the ground-state valence band, it may be trapped and creates electron-hole pairs. This recombination gives rise to photonic...

Complete CL Solutions with Powerful Mapping Capabilities Hyperspectral mapping To further expand the capabilities of your CLUE system, HORIBA Scientific offers a simple solution to faster mapping by synchronizing the scanning of the electron beam to your spectrometer. Thus full spectral data can be acquired either from discrete areas or during mapping, enabling CL measurements in optimal conditions during acquisition. (Data courtesy of Dr. Jean-Daniel Ganiere EPFL Switzerland) A complete CL spectrum is obtained for each point on the sample. The CL hyperspectral image is reconstructed in...
