Abstract
Thus far, all reported work on luminescence petrography has been accomplished by use of the microprobe, a very expensive instrument beyond the grasp of most petrographers. A simple device is described here which attaches to an ordinary petrographic microscope and permits luminescent observations as well as ordinary white or polarized light observations. The instrument has the advantages of short pump down time (two min), large area of illumination by the electron beam (1×3 cm), and a minimum of charging and sparking problems. In addition, ordinary uncoated rock or mineral thin sections may be used. The instrument has proven to be superior to the microprobe for luminescent observations of geological specimens. Other (nongeological) applications in fields such as ceramics and solid state physics are also likely.
