Typical Applications • Fiber coupled diode lasers • Couplers and pump combiners • Beam delivery cables • Spectroscopy and instrumentation NuBEAM 400 pm 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. This fiber features a 400 micron core diameter, 0.22 NA and 660 micron clad diameter with a silicone coating and a transparent nylon buffer. This fiber is 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. Features & Benefits • Robust industry standard design — Compatible with majority of fiber interconnect systems • Exceptional geometric uniformity and core/clad concentricity — Ease of assembly • Clean room fiber draw — Eliminates coating "hot spots" • Pure Silica Core — High resistance to optical damage Optical Specifications Operating Wavelength Core NA OH Level Geometrical & Mechanical Specifications First Cladding Diameter (inner) Second Cladding Diameter Core Diameter First Buffer Diameter Second Buffer Diameter First Buffer Material Second Buffer Material Short Term Bend Radius Long Term Bend Radius Prooftest Level 453.0 ± 13.0 pm 672.5 ± 12.5 pm 408.0 ± 8.0 pm 780.0 ± 20.0 pm 1100 ± 55 pm Silicone Transparent Nylon > 66 mm > 198 mm > 100 kpsi (0.7 GN/m2) qUFERN Buffer Requirements: Silicone Primary Buffer, Transparent Nylon Outer Buffer Low or High -OH Core: Low Matched or Depressed Cladding: Depressed Special Core Dopants: Pure Silica Core 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 • E-mail info @ nufern.com • www.nufern.com • Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
