Cathodoluminescence Microscopy (CL)
The Petroleum Geosciences Program recently acquired a Relion Cathodoluminescence System, which has been mounted on an Olympus BX41 polarizing microscope.
Introduction
Cathodoluminescence is an optical and electrical phenomenon created when a beam of electrons, generated by an electron gun, impacts a luminescent material. This causes the material to emit visible light.
CL microscopy is a tool used to study the microstructure and composition of rocks and fossils.
A cathodoluminescence microscope enables the observation of structures and fabrics within crystals that cannot be seen using normal light. For example, valuable information on the growth history of minerals in a rock can be obtained thus allowing the user to characterise the burial history. The CL microscope is used in classes and research.
