Cathodoluminescence images made using a CL device attached to a scanning electron microscope (SEM).
(mostly older images, but I don't have much time for updates)

Why Scanned CL?

sandstones zircons volcanics carbonates metamorphics intrusives

Most of these images were taken using filter monochromators which allow successive images to be combined to form a color image of the luminescence. Semi-technical details are available.
