1. An endoscope for imaging a target region within a body, comprising:
a tip member comprising one or more light emitting devices configured to direct illumination to at least a portion of said target region, said tip member also comprising a front window disposed so as to receive light from said target region when said tip member is in said body, said tip memeber further comprising a prism for redirecting light transmitted through said front window, said tip member comprising a housing that supports said one or more light emitting devices, said front window, and said prism;
an elongated member having proximal and distal ends, said tip member at said distal end;
a plurality of lenses disposed along an optical path in said elongated member so as to receive light from said prism that is transmitted through said front window and configured to convey the received light toward the proximal end of the elongated member;
a lens tube including some of said plurality of lenses therein; and
a spacer comprising a separate component from said tip member and said lens tube configured to connect said lens tube to said housing of said tip member, and to establish a proper distance and provide alignment between optics within said tip member and said lens tube.
