Advantages of SPARC Spectral

Ensures the best data quality

Tailored to your research needs

Future-proof and easily upgradeable

Customizable for your research needs

Use up to six different CL imaging modes with the most flexible and modular CL detector on the market, including fast-intensity imaging, angle-resolved imaging, and CL spectroscopy to meet your research needs. Additionally, you can gain further insights into dynamical processes in materials by performing time-resolved CL.

Sensitive and efficient CL detection

Experience the best data quality with the SPARC Spectral, ensured by its broad spectral range, unsurpassed sensitivity, and high-quality parabolic mirror. The SPARC Spectral is easily retrofitted to your SEM and compatible with SEMs from all the major brands.

Easy-to-use software

The SPARC Spectral comes with ODEMIS, our powerful open-source software with a multitude of imaging modes, as well as data visualization and analysis. The free software ensures user-friendly acquisition and data analysis, allows scripting, and provides updates and new features free of cost, helping you answer your unique research questions.

Trusted by researchers in the field

“I ultimately chose Delmic because the Delmic system is modular: One can purchase and update the system incrementally.”

Prof. Nahid Talebi Kiel University

"The SPARC system is an elegant way to extend the microscopic analysis we perform using other methods."

Priv.-Doz. Dr. Daniel Abou-Ras Helmholtz-Zentrum Berlin

"It was very reassuring to know that the SPARC system was developed by a trusted and esteemed colleague in our field, rather than being some general-purpose solution in material science."

Dr. Saskia Fielder University of Southern Denmark, SDU
