Abstract

An aperture device for a flow cytometer is described. The aperture device includes a first aperture, and a second aperture spaced apart from the first aperture by a distance. The distance between the first and second apertures and a size of the first and second apertures are adjustable to create an optimal light intensity fringe pattern for analyzing a particle having a preselected type or characteristic at an interrogation zone of the flow cytometer.
