LightPath IsoBeam Fusion Collimators

LightPath's® new IsoBeam Fusion™ Collimators combine a high power optical isolator in line with a Fusion™ fiber collimator. The optical isolator acts to suppress back reflection and backscattering - an especially useful feature for fiber lasers. Without this protection, fiber lasers could easily be damaged when working at high peak power (such as in etching and marking applications).

The 1064nm high power isolator features very low insertion loss, high isolation, high power handling, minimal return loss and excellent reliability and environmental stability. The collimator features LightPath's® Fiber Fusion™ technology, where the lens is laser fused directly to the tip of the fiber, virtually eliminating back-reflections without the need to angle cleave the fiber. That, in turn, allows the optical system to remain coaxial through the isolator, keeps return loss very low, and greatly increases the overall reliability of the assembly.

Standard configurations are available for 0.5mm and 1.0mm beam diameters. LightPath® also has the capability to produce custom designs to your specifications with different beam diameters, fiber types, higher power handling capability, and other options.
