1. An apparatus, comprising:
illumination optics comprising a focusing lens, the illumination optics having an f-number;
a spatial light modulator (SLM) optically coupled to the focusing lens and to the illumination optics, the SLM comprising pixels on a surface of the SLM, wherein the focusing lens is tilted at an incident angle relative to the surface of the SLM;
an actuator optically coupled to the SLM; and
projection optics optically coupled to the actuator, the projection optics having an f-number, the f-number of the illumination optics greater than the f-number of the projection optics.
