Claim:
1. A device comprising: a treatment laser source; pair of 2 scanning mirrors downstream in an optical path of a laser beam from the treatment laser source, the pair of scanning mirrors being independently controllable to be moved to multiple positions defined by scanning mirror positions; the pair of 2 scanning mirrors producing an astigmatic pupil from a laser beam of the treatment laser source a first lens system downstream from and in the optical path of a laser beam from the pair of scanning mirrors, the lens system comprising one or more lenses; further comprising a second lens system in the optical path and downstream of the first lens system, the second lens system adjusting the light beam from the first lens system such that a light beam from the second lens system converges as a pupil on a delivery mirror; the first lens system and the second lens system together converting the astigmatic pupil to a non-astigmatic pupil; the delivery mirror being positioned downstream in the optical path of the second lens system, the delivery mirror delivering a laser beam from the first and second lens systems onto the target tissue; wherein the lens system forms a static pupil on the delivery mirror which is independent of any movement, position or pattern defined by the multiple positions of the pair of 2 scanning mirrors.
