Couplers using GRIN lenses, achromats, aspheres, fused silica, plano-convex, and biconvex lenses have all been made utilizing this design. Non-contact style couplers can handle input powers of up to 100 W CW, and even higher energies from pulsed sources. Thorlabs offers a variety of fiber collimation and coupling solutions. FiberPorts can be used to provide a stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated fiber with five or six directional adjustments. How to Transforms a Collimated Laser Beam with Elliptical Cross-section into a Circular Beam or Vice Versa. How measured fiber parameters help to. What is a Fiber Collimator? It is often necessary to transform the light output from an optical fiber into a free-space collimated beam. In principle, a simple collimation lens (see Figure 1) is sufficient for that purpose.
