This book offers a comprehensive introduction to confocal microscopy – with a particular focus on spectral confocal microscopy. Beginning with an introduction to optical lenses, it provides a guide to compound microscopes and explains related topics like microscopic resolution. It then presents an outline of fluorescence and its corresponding implications for microscopy. The following excursus on the confocal beam paths includes implementation of acousto-optical devices and modern sensor techniques. Complex relationships are explained in a comprehensible manner, supported by many graphical figures. 

Discussing the principles of magnifying optics and the technical fundamentals and modes of operation of modern laser scanning microscopes, it is a valuable resource for student and lab technicians as well as faculty members.
