Abstract
A device comprising: an optical subassembly has a lens rear surface including one or more facets for scattering at least some of the light transmitted through the lens rear surface.
Claims6
An optical subassembly device comprising:
- a fiber receptacle for receiving an optical fiber, located on a distal end of the optical subassembly, wherein the fiber receptacle has a fiber axis, and wherein the fiber receptacle has a recess extending into an interior end surface of the fiber receptacle;
- and
- a lens having an optical axis, located on a proximal end of the optical sub-assembly, for focusing a light beam traveling through the optical subassembly;
- wherein the lens has a rear surface at a proximal end of the recess;
- wherein the lens rear surface includes a plurality of facets that are angled with respect to the fiber axis of the fiber receptacle, and wherein the lens rear surface is a radial accordion surface.
