Focal plane shift elements and optical systems with focal plane shifting features for illuminating flow-paths in a fluidic processing system are disclosed. An optical system may include a light source providing an incident first light beam. The optical system may include at least one optical element configured to collect and focus the incident first light beam to produce a second light beam having different portions simultaneously focused at two or more different locations along an optical path, with each location corresponding to a different flow-path of the fluidic processing system. The focal plane shift elements and optical systems with focal plane shifting features may be particularly useful in a microfluidic system. |
