Monarc
Cathodoluminescence system for SEM
The new Gatan Monarc pushes the boundaries of what’s possible with a SEM-based cathodoluminescence system. With a boost in sensitivity and spectral resolution, it’s truly a next generation instrument:
- Unmatched spatial (<10 nm), angular (1°) and wavelength (0.1 nm) resolution
- Capture angle- and wavelength-resolved CL data simultaneously
- Collect hyper-spectral data up to 30 times faster than other CL detectors
Easy to Use
- Automated alignment and recipes for the best results
- Permanently aligned optics for reproducibility
- Large field of view to increase productivity
Accurate Correlation
- Detect multiple signals simultaneously
- Correlated imaging of physical properties and composition with CL data
- Full use in-lens SEM detectors during CL measurements

Unique Capabilities
Angle-Resolved (ARCL)
- Study how light and matter interact far below the optical diffraction limit.
- 400x larger field of view than other CL detectors with very similar resolution (patent pending)
Wavelength- and Angle-Resolved (WARCL)
- Examine how light and matter interact at multiple viewing angles and wavelengths
- Achieve previously impossible visualisations and studies, due to Monarc’s unique optical design
Polarisation Filtering
Determine the emission polarisation properties of deep sub-wavelength structures, such as:
- Ooptical nanoantenna
- Nano-cavities
- Photonic crystals
Near-complete characterisation of emission from a thin-film InGaN-based LED. Acquired with Monarc’s unique wavelength- and angle-resolved spectroscopy mode. Interference between emitted and reflected light rays creates an emission pattern that varies according to the wavelength.
Two models are available, each suited to a different application area:
Monarc
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.
Monarc Pro
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.
