Abstract: A projection system, configured to project a radiation beam onto a target, includes a rotatable frame configured to rotate about an axis defining a tangential direction and a radial direction, wherein the rotatable frame holds a lens configured to focus the radiation beam in only the tangential or radial direction; and a stationary part comprising a substantially stationary lens configured to focus the radiation beam in only the other of the tangential or radial direction.
