1. A multiple wavelength LED array illuminator for providing light along an optical axis, comprising:

  • a substrate;

    at least one array of multiple LED chips without individual packaging supported by said substrate, wherein the LED chips emit light within different wavelength ranges and are distributed laterally with respect to said axis over an area, said LED chips having light emitting surfaces for emitting light in directions transverse to said area; and

    an optical element adjacent to the light emitting surfaces of the LED chips in said at least one array that collects and directs light emitted by the LED chips of the at least one array along said axis towards a target.
