Cathodoluminescence (CL)
Cathodoluminescence (CL) imaging utilises visible light emitted by the specimen. As the wavelength and intensity of light emitted are determined by the chemical composition and defect structure of a sample, CL imaging is a very powerful tool for observing fine-scale and subtle variations in its composition. ISAAC instruments have been used to image a wide range of materials, including different generations of quartz in sandstones, and growth zoning in calcite, zircon, and diamond. ISAAC’s optical cathodoluminescence microscope can be used in conjunction with the SEM’s for comprehensive sample characterisation.
