a light source configured to provide illumination light;
a spatial light modulator positioned to receive the illumination light; and
an optical assembly including an optical element and a curved reflector that is distinct and separate from the optical element, the curved reflector being disposed relative to the light source so that at least a portion of the illumination light is reflected by the curved reflector toward the optical element, is reflected by the optical element toward the curved reflector, and is transmitted through the curved reflector,
