Practical Scanning Electron Microscopy: Electron and Ion Microprobe Analysis

by Joseph Goldstein

In the spring of 1963, a well-known research institute made a market survey to assess how many scanning electron microscopes might be sold in the United States. They predicted that three to five might be sold in the first year a commercial SEM was available, and that ten instruments would saturate the marketplace. In 1964, the Cambridge Instruments Stereoscan was introduced into the United States and, in the following decade, over 1200 scanning electron microscopes were sold in the U. S. alone, representing an investment conservatively estimated at $50,000- $100,000 each. Why were the market surveyers wrongil Perhaps because they asked the wrong persons, such as electron microscopists who were using the highly developed transmission electron microscopes of the day, with resolutions from 5-10 A. These scientists could see little application for a microscope that was useful for looking at surfaces with a resolution of only (then) about 200 A. Since that time, many scientists have learned to appreciate that information content in an image may be of more importance than resolution per se. The SEM, with its large depth of field and easily that often require little or no sample prepara interpreted images of samples tion for viewing, is capable of providing significant information about rough samples at magnifications ranging from 50 X to 100,000 X. This range overlaps considerably with the light microscope at the low end, and with the electron microscope at the high end."

About the author

Joseph Goldstein (born 1944) is one of the first American vipassana teachers (Fronsdal, 1998), co-founder of the Insight Meditation Society (IMS) with Jack Kornfield and Sharon Salzberg, contemporary author of numerous popular books on Buddhism (see publications below), resident guiding teacher at IMS, and leader of retreats worldwide on insight (vipassana) and lovingkindness (metta) meditation.

While the majority of Goldstein's publications introduce Westerners to primarily Theravada concepts, practices and values, his 2002 work, "One Dharma", explored the creation of an integrated framework for the Theravada, Tibetan and Zen traditions.
