Simultaneously shaping both the luminous intensity and the wavefront of light with freeform optics holds significant potential across numerous applications. However, flexible intensity and wavefront shaping (e.g., generating a predefined intensity with an engineered freeform wavefront) in tilted geometries remains an unresolved problem. Here, we propose a direct method that is built upon the Monge–Ampère method developed for point-source intensity tailoring to address this problem. This direct method enables flexible intensity and wavefront shaping in tilted geometry with two freeform surfaces. Two examples are given to validate this method via both simulation and experimental tests.
