Product information "LPSC Laser to Fiber Couplers"
Pigtail Style; 200 to 2100 nm; Coupling Efficiency >60% to >80%; Backreflection -35 to -60 dB; Power Handling >1 to > 100 W
OZ Optics' LPSC pigtail style laser to fiber couplers are recommended for permanent or semi-permanent situations, where optimum coupling efficiency, output stability, and minimum backreflection are desired. In these couplers the fibers are permanently glued to the focusing lens. The fiber-lens assembly is then inserted into the tilt adjustment flange and held in place with two radial set screws. Because the fiber is permanently attached to the lens, the fiber cannot be replaced without also replacing the coupling lens.
In pigtail style couplers the internal endface of the fiber is polished at an angle to reduce backreflection. This ensures <-40 dB backreflection. By adding an anti-reflection coating to the inner fiber tip, backreflection can be further improved to -60dB.
