title: A simple, combined diffractometer and scanning microdensitometer.
abstract: A simple device for densitometering electron micrographs or other transparencies by one-dimensional scanning is described. Micrographs of crystalline materials are oriented by means of their optical diffraction patterns displayed with a slightly modified microscope.
