Cathodoluminescence

Modular CL in-SEM system with multiple imaging modes

Contact
Cathodoluminescence imaging is also an ideal tool to study geological samples. The CL emission from a rock gives insights into crystal growth, zonation, cementation, replacement, deformation, provenance, trace elements, and defect structures. This can be used to fingerprint rocks and reveal interesting spatial textures on a submicron scale. The SPARC is a seamlessly integrated CL system, compatible with full-sized SEMs, offering multiple imaging modes on a modular platform.
