Abstract
An optical system and luminaire are provided that include a light source and a beam adjuster optical element (BAOE). The light source emits a source light beam that is received by the BAOE, which emits an adjusted light beam. The BAOE includes an outer portion that receives an outer portion of the source light beam and causes light rays of the outer portion to diverge in a corresponding outer portion of the adjusted light beam and an inner portion that receives an inner portion of the source light beam and causes light rays of the inner portion to converge in a corresponding inner portion of the adjusted light beam. The luminaire includes an actuator that moves the BAOE within the luminaire and a control system that receives a control signal via a data link and moves the BAOE in response to the control signal.
