The second set of magnetic lenses that control the probe current/probe size. In this FE-SEM, the operation mode determines whether the two condenser lenses are working separately or together. These ...

Providing an introduction to the theory and current practice of electron microscopy, this text shows how principles of electricity and magnetism, optics and modern physics have been used to develop ...

Achromatic lenses and semi-plan lenses are used to improve the alignment of colors at the focal point in order to provide a clearer image. They differ in terms of glass type, cost, and index of ...
