1. A scanned beam imaging tip, comprising:

  • a single mode optical fiber operative to transmit light to a distal end;

    a focusing lens aligned to receive light from the distal end of the single mode optical fiber;

    a meniscus lens having a semi-reflective inner surface aligned to receive light from the focusing lens and reflect at least a portion of the received light; and

    a MEMS scanner aligned to receive light reflected by the inner surface of the meniscus lens and reflect the light toward a field-of-view and operable to scan the light over a two dimensional field-of-view; and

    wherein the meniscus lens is operative to shape the light scanned by the MEMS scanner into a beam having a desired shape.
