Color Cathodoluminescence Imaging with the ChromaCL2 iBSED Detector

The ChromaCL2™ iBSED detector provides scanning electron microscope (SEM) live color cathodoluminescence imaging.


The ChromaCL2 iBSED detector is a color cathodoluminescence imaging device developed for use in SEMs. Color cathodoluminescence (CL) imaging can reveal geochemical processes in various petrographic and earth scientific applications.

  • It displays macro- and micro-texture in sedimentary rocks, including sediment source, compaction degree, diagenetic history, authigenic and detrital mineral differences, cementation history, and authenticity
  • With a single electron beam pass, users can snap topography, composition, and color CL images all at once
  • Easy to use
  • Color cathodoluminescence images assist in determining the presence of geochemical differences
  • High-efficiency detection allows for the shortest time-to-data, images with the maximum spatial resolution, and less data misinterpretation owing to e-beam damage
  • Carbonate imaging kit for detecting phosphorescence in scanned CL images caused by particular carbonate minerals
  • The field stitching software module enables users to have a limitless field of view

Episode 5: Analyzing CL Data

Cathodoluminescence Explained. Episode 5: Cathodoluminescence Data Analysis

Cathodoluminescence Explained. Episode 5: CL Data Analysis. This webinar focuses on the importance of CL data analysis, which may include spatial, spectral, and angular information, or any combination thereof. The importance of data analysis of such CL data can be nearly as important as data acquisition and can reveal many interesting characteristics of a specimen including the influence of constituent concentration and distribution, defect density, plasmonic or photonic modes, and more. During this webinar, analysis of data drawn from various specimens is performed, their results discussed, and the benefits of such analysis demonstrated. Video Credit: Gatan, Inc.
