Abstract

A solid two-beam Sagnac-type interferometer is described that is especially adapted for use with a microscope for Fourier excitation and emission fluorescence spectroscopy. Its advantages are its compactness and stability, and because it is an integral optical element, the need for eliminating vibration and for shielding from air currents is greatly reduced.
