Smart Product Number: BD-S50/70/480-STN
NuBEAM 50 µm Core Beam Delivery Fiber
Nufern's beam delivery NuBEAM specialty multimode step-index fibers are designed for compatibility with the majority of fiber interconnect systems and diode laser power delivery systems. These fibers feature a 50 micron core diameter, 0.22 NA and are available in three different clad diameters with a silicone coating and a transparent nylon buffer. These fibers are also available with Nufern's proprietary NuCOAT-FA coating for added power confinement or polyimide for high temperature applications. Additional clad diameters and different NAs are available upon request.
