Effortless CL intensity detection

Use JOLT for rapid and convenient CL detection. Gain valuable insights into geological materials by mapping the emitted CL intensity to reveal properties such as crystal growth, zonation, deformation, and defect structures. Additionally, you can measure the CL emission of bulk materials such as semiconductors and rare-earth doped materials.

Advantages of JOLT

list-arrow Rapidly obtain micro- and nanoscale insights

list-arrow Efficiently screen your materials for further analysis

list-arrow Easy integration and operation


Direct CL detection in your SEM

JOLT is an entry-level cathodoluminescence detector that offers two versions: a panchromatic detector and an RGB (colored CL) detector. It provides direct CL detection without any moving parts. Integration into your SEM couldn't be simpler as JOLT is compatible with all SEM brands and mounted on a single vacuum port.


Combine with other techniques

To gain deeper insights into the properties of your sample, combine JOLT with other SEM-based techniques for correlative imaging, or use it as an effective screening tool for advanced characterization techniques such as mass spectrometry.
