Claim 10:
11. A lens assembly for use in a medical device, the lens assembly comprising:
a unitary and monolithic barrel having a length, a proximal end, a distal end, a radially inward facing surface surrounding a passageway, and a radially outward facing surface, wherein the passageway includes a central portion between distal and proximal ends of the passageway, wherein the central portion includes a proximal portion with a first diameter, an intermediate portion with a second diameter, and a distal portion with a third diameter, and wherein the first, second, and third diameters are different, wherein the second diameter is larger than the first diameter and the third diameter, and wherein the barrel further comprises a first projection, a second projection, and a third projection;
a first lens in the passageway of the barrel, wherein the radially inward facing surface of the barrel is configured to hold the lens, and wherein the first projection is a seat for the first lens;
a second lens in the passageway of the barrel and positioned at the distalmost end of the barrel, wherein the second lens (i) abuts a planar, distal-facing surface of the second projection and (ii) protrudes distally out of the barrel;
a holder configured to receive the barrel and having a radially inward facing surface, a proximal end, and a distal end;
an adhesive layer on both 1) the radially inward facing surface of the barrel, and 2) the radially inward facing surface of the holder; and
a detector array at the proximal end of the holder;
wherein the first lens is positioned between the proximal portion and the intermediate portion; and
wherein the second lens is positioned between the intermediate portion and the distal portion.
