| Non-Contact Style Receptacle Style Collimators and Focusers |

-
In non-contact style source couplers, an air gap exists between the fiber and the lens.
-
This design is more flexible, allowing a wide range of lens types and focal lengths to be used.
-
The distance between the fiber and the lens can be adjusted to compensate the changes in the source wavelengths or to intentionally defocus the laser beam to prevent arcing in high power laser to multimode fiber applications.
-
Couplers using GRIN lenses, achromats, aspheres, fused silica, plano-convex, and biconvex lenses have all been made utilizing this design.
