A lens assembly for a near range camera includes a lens stack diposed in a tubular lens housing. The lens stack includes several lenses in a stacked arrangement. An outermost lens of the lens stack is disposed in an open end of the lens housing, and a second lens of the lens stack abuts an inward facing surface of the outermost lens along an annular region of contact between the outermost lens and the second lens. A seal is provided along the annular region of contact. In some embodiments, the seal is formed by fusing the first lens to the second lens along the annular region of contact.
