ABSTRACT:
A first part has first, second and third inwardly-facing surface portions angularly spaced about an axis, and a second part has outwardly-facing fourth, fifth and sixth surface portions spaced angularly about the axis, a radial distance from the axis to each surface portion decreasing progressively in a given direction along the axis. Each of the fourth, fifth and sixth surface portions faces, is closely adjacent to, and is substantially congruent in shape with a respective one of the first, second and third surface portions. At least one of the first and second parts is an optical component.
