Abstract: In some aspects, a flow cytometer system is provided that includes beam shaping optics positioned to manipulate a light beam and produce a resulting light beam that irradiates the core stream at the interrogation zone of the flow cell. The beam shaping optics include an acylindrical lens positioned to receive and focus light in a direction of a first axis orthogonal to a direction of light travel, and a cylindrical lens positioned to receive the light output from the acylindrical lens and to focus the light output from the acylindrical lens in a direction of a second axis orthogonal to the first axis and to the direction of light travel.
