Microscopy is a dynamic area of science, incorporating both basic classroom microscopes and sophisticated research style instruments that can be driven by light, electrons, or X-rays. The rate of advance in the area over the last 50 years has led to a number of technological advances. In this Very Short Introduction Terence Allen, an established expert on microscope techniques, describes the scientific principles behind the main forms of microscopy, and the exciting new developments in the field. Focusing on the main underlying principles, and introducing the power of what is achievable today using microscopes, Allen demonstrates how microscopy impinges on almost every aspect of our daily lives; from medical diagnosis to quality control in manufacture. Beginning with a brief history of the early stages of microscopy development, Allen then concludes with a comprehensive account of the diverse spectrum of microscopy available today.
