Abstract

Many illumination problems in microscopy can be solved easily and economically with fiber optics. Modes of illumination not provided by the designers of a microscope can be added. A modular illumination system involving a number of microscopes and sources can be assembled. Various types of illumination can be used simultaneously, e.g., bright field and dark field, transmitted and reflected. Realignment on changing lamps is simplified, since it is merely necessary to align the lamp relative to the fiber input end. Older microscopes with small lamps can be upgraded by using a fiber bundle terminated at the lamp filament location.
