ABSTRACT:
A lens system includes a body member holding at least one micro lens array. The micro lens array has a first surface with a plurality of micro lenses arranged in a row and a second surface opposing the first surface. The second surface is under an angle towards the first surface. Furthermore the lens system comprises either: (i) a plurality of ferrules enclosing end-portions of light waveguides, or (ii) a plurality of light waveguides without ferrules, wherein the ferrules or light waveguides are adhesively fastened in a spaced relationship from each other to the second surface of the micro lens array preferably by means of an adhesive, by bonding or by welding.
