Transmission Electron Microscopy,-emission type the specimen itself is the source of radiation.. The field-emission microscope, employing no lenses, will be discussed in Chapter 14. The transmission electron microscope and the scanning electron microscope (see Chapter 13) employ focusable lenses.

In actuality, microscopy is both objective and sub- jective; it is seeing through an instrument by means of the eye, and more importantly, the brain. The function of the brain is to interpret the eye‘s image in terms of th

Being of very high or ultrahigh frequency, 100–1000 megacycles/sec or megahertz (MHz), the microscopical acoustic waves are ultrasonic; they cannot be hea
