Abstract
The present invention provides improved collimating lens assemblies () which include: a singlemode fiber () terminating in a distal end; a step-index multimode fiber () having a proximal end abutting to the singlemode fiber distal end, and having a distal end; a graded-index multimode fiber () having a proximal end abutting the step-index multimode fiber distal end, and having a distal end; and a collimating lens () longitudinally spaced from the graded-index multimode fiber distal end by an intermediate air gap (), and operatively arranged to collimate light rays emanating from the graded-index multimode fiber distal end. The improved collimating lens assembly is characterized by the fact that there is no epoxy, silicone gel or index-matching material between the graded-index multimode fiber distal end and the collimating lens.
