Abstract

A flow cytometer can include: at least one light emitter configured to emit light in a light path; a rectangular flow cell having flow cell width that is substantially lateral to the light path and a flow cell depth that is longitudinal to the light path, wherein the light path has an interrogation width at the flow cell that is narrower than the flow cell width; and a spherical reflector positioned adjacent to the rectangular flow cell and having a concave reflective surface that has a reflective direction that is positioned substantially orthogonal with the light path such that reflected light is reflected along a reflected path that is substantially orthogonal with the light path. At least one light absorbing member is positioned at least partially around the reflected path to absorb reflected light at an angle to the reflected path.
