Abstract

Confocal fluorescence imaging is widely used, particularly for biological applications, and also notably in direct-view microscopes. Recent work has compared the use of coherent and incoherent illumination sources on the optical sectioning characteristics of fluorescence direct-view microscopes. However this detailed comparison has been done in theory. This paper addresses the experimental aspects of using coherent light sources in fluorescence imaging using a range of finite-sized, multiple-aperture arrays. The experimental difficulties of choosing a suitable uniform, flat, fluorescent plane with a high quantum efficiency are considered. Axial response curves obtained with a fluorescent laser dye sample are presented.
