LIEKKI™ Passive Fibres
| nLIGHT’s passive LIEKKI™ fibers are especially designed and manufactured to match commercially available active fibers. The core diameters and numerical apertures are perfectly matched to the active fibers to ensure that excellent beam quality is maintained throughout the system. LIEKKI™ passive fibers are available in single cladding, double cladding (DC), single cladding polarization maintaining (PM) and double cladding polarization maintaining configuration. Many of the fibers are also available as a Photosensitive variant for Fiber Bragg Grating manufacturing. Please contact sales representative for the availability. |
