This phenomenon is called . if the emission takes place very shortly after the absorption of light; it is called . or . where the emission is significantly delayed. All these phenomena, taken together, are called .. To generate luminescence an external energy source, for instance a lamp, is necessary.

The light microscope as a tool for observation and measurement: illumination and image formation,When a light wave strikes an object, different kinds of interaction may take place, resulting in a modulation of the illuminating rays. These interactions may be a factor in image formation, but they can also be a disturbing element.

These laws will be dealt with briefly in this first chapter since they provide the foundation for the construction and the functioning of the microscope. The long and continuing development of the microscope has been the result of

Consequently, a transparent object such as a tissue section will give an image which is poor in contrast and yields little information. By reducing the aperture of the illumination beam by means
