Delmic CL solutions offers a range of powerful and user-friendly cathodoluminescence detectors, which can help you learn more about both bulk and nanostructured materials.
The electron beam that is used in cathodoluminescence (CL), acts as a highly localized broad-band excitation source. This makes CL ideal for characterizing spectral characteristics of optical resonances in dielectric resonators used as building blocks for e.g. metasurfaces and sensors. Furthermore, it can be used to map dispersion, directionality, and polarization in waveguides, dielectric metasurfaces, photonic crystals, and photonic topological insulators to name a few examples.
