Pushing the boundaries of cathodoluminescence detection


The SPARC Compact pushes the boundaries of compact cathodoluminescence (CL) imaging performance. It features the proven ease-of-use, high-collection efficiency and fast time-to-image of any DELMIC system. Without compromising on high performance, this is a small-scale version of the SPARC cathodoluminescence system for researchers in geology and materials science who specifically require intensity measurements by a photomultiplier tube.

The SPARC Compact features a range of opportunities that combines ultimate performance with reliability, and enhances the analytical capabilities at the disposal of today’s microscopists.

SPARC Compact CL detector

Modular and upgradeable

The SPARC Compact is a cathodoluminescence system that works out of the box and can be upgraded to high-performance angle-resolved CL imaging and hyperspectral CL imaging. Its modular design makes it easy to extend and add features to the system as research evolves.

This cathodoluminescence detector can also seamlessly be combined with other scanning electron microscope (SEM) detection modalities, thus making it a truly multifaceted solution.

Optimized for your research


PMT Fast-intensity mapping imaging mode

Fast-intensity mapping imaging mode

A fast analog PMT detector can be used for large-scale imaging. This allows for the rapid inspection of large areas, ideal for geological applications, fast device inspection, and efficient region-of-interest finding. A filter wheel can be used for spectral differentiation.


ODEMIS software

ODEMIS is a software package which is being used for all Delmic microscopes to analyze the imaging workflow. The modular approach in combination with the open-source acquisition software ODEMIS ensures a user-friendly solution that can serve a broad user base as well as delivering a system that is a truly unique and versatile research instrument.


For the SPARC Compact system, the software is specifically designed for the acquisition of intensity maps based on point-by-point scans, spectral differentiation based on filters in a filter wheel, and drift correction.
