ABSTRACT:
An adaptive gas lens provides a radial flow of gas that makes phase corrections on a distorted annular wavefront passing therethrough. A flexible flange controlled by precision actuators provides for variation in gas stream width yielding variations in the optical path difference over a range of azimuthal periods.
