Period

1959-1968

Canada

Used in research related to the forest industry and forest products. Canadian research and Canadian scientists played a major role in demonstrating the commercial viability of the scanning electron microscope. (Smith history- in supp. info.)

Function

With a S.E.M. the surface of a solid sample is bombarded with a fine probe of electrons. The sample emits secondary electrons that are generated by the action of the primary beam. These secondary electrons are collected & amplified by the instrument. Since the beam strikes only one point on the sample at a time the beam must be scanned over the sample surface in a raster pattern to generate the picture.

Technical

A very early S.E.M. The first commercial S.E.M. was not announced until 1965. (see supp. inf. for further information, ref.1)
