ABSTRACT:
A first sub-lens having two opposite first surfaces is provided. One of the first surfaces has a central bulged first optical surface for refracting light rays passing therethrough and defining a first optical axis. The other first surface defines a recess that defines a flat bottom surface. A second sub-lens having two opposite second surfaces is provided. One of the second surfaces has a central bulged second optical surface for refracting light rays passing therethrough and defining a second optical axis. The other second surface is flat and substantially similar to the bottom surface of the first sub-lens in shape and size and is glued to the bottom surface of the first sub-lens in a manner that the first axis is coaxial with the second axis.
