The Rainbow Series Cathodoluminescence Imaging and Spectral Detection System can be integrated with scanning electron microscopes or focused ion beam systems to achieve full-spectrum and single-spectrum scanning imaging, spectral acquisition, and hyperspectral analysis of cathodoluminescence. The system is equipped with a fluorescence collection mirror, transmission optical fibers, a signal conditioning and acquisition system, an electron beam scanning generator, and a spectrometer, all controlled through integrated system control and acquisition software.

The system utilizes the electron beam scanning generator to control the electron beam scanning of the electron microscope and to trigger the detectors. Simultaneously, it can collect fluorescence intensity signals obtained through the signal conditioning and acquisition system, ensuring strict synchronization between the electron beam scanning signal and the detector data acquisition. This allows for the acquisition of cathodoluminescence imaging and cathodoluminescence spectral surface distribution data. The system enables cathodoluminescence imaging and spectral measurements of various materials at nanoscale spatial resolution. It is particularly well-suited for research in semiconductor materials, optoelectronic materials and devices, nanophotonics, thin films, nanostructures, and minerals.
