False-colour scanning electron micrograph (SEM) of two strands of merino sheep wool, showing the typical overlapping scales of animal hair. Magnification: x2000 at 4x4-inch size, x700 at 35mm size. (The colour has been generated by the microscope itself, using two detectors to record backscattered electron (BSE) signals from the specimen. This colouring technique was developed in 1985 by Dr Danilatos of the CSIRO Division of Textile Physics, Australia; he calls it environmental SEM or ESEM.)
