Abstract
An optical system is provided which comprises: a light source () for emitting light beam; an optical main axis; an optical shaping element () for shaping a light beam facing the light source () and directly adjacent to the light source (), wherein the optical shaping element () includes a first freeform surface facing the light source (), the light beam is shaped by means of the first freeform surface of the optical shaping element () in such a way that light intensity of the light beam has a flat-top profile on a first axis which is perpendicular to the optical main axis. With this optical system, a desirable light intensity profile can be achieved by using only a single optical element. Moreover, a flow cytometer including this optical system is provided.
