With unmatched spatial, angular and wavelength resolution.

The Gatan Monarc pushes the boundaries of what’s possible with a SEM-based cathodoluminescence system. It’s a next generation instrument with a boost in sensitivity and spectral resolution.
With unmatched spatial, angular and wavelength resolution.
Capture data simultaneously
Compared to other CL detectors
Determine the emission polarisation properties of deep sub-wavelength structures, such as:
For geoscience and mapping applications
The Monarc surpasses previous SEM CL detectors with the largest field of view, independent of spectral resolution. Hyperspectral data is collected with greater spatial sampling, using new wavelength-filtered spectrum imaging technology.
For nanophotonic and optoelectronic material applications
This model delivers the greatest sensitivity and spectral resolution of any CL system available. You’ll also benefit from unique wavelength- and angle-resolved analysis and polarisation-filtering options.
We offer a range of instruments for elemental and mineral analysis, mapping and imaging in geology and geoscience.
Cathodoluminescence (CL) is a technique for characterising composition, optical and electronic properties with data that correlates with morphology, micro-structure, composition and chemistry at the nanoscale.
Find out all about CL with Gatan's new website for users and for those new to the technique.
How cathodoluminescence can be used to study the emission patterns of nitride semiconductor micropillars for microLEDs in displays, including wearable devices.
Cathodoluminescence can be used to study crystal structure orientation - in this example we look at how it can be used on a geological sample.
Map defect distribution and variations for process development of materials for electronic / optoelectronic devices. CL is ideal for materials not suitable for photoluminescence spectroscopy.
It's now much easier to achieve high quality results with SEM-based cathodoluminescence, with the new Gatan Monarc. This has valuable applications in geology and geoscience, for rocks and minerals analysis.
