NuBEAM 50 μm Core Beam Delivery Fibers

Product catalog summary
Overview: Nufern's NuBEAM 50 µm Core Beam Delivery Fibers are specialty multimode step-index fibers designed for compatibility with most fiber interconnect and diode laser power delivery systems. These fibers feature a 50 micron core diameter and 0.22 NA, available in three different clad diameters with silicone coating and transparent nylon buffer. Additional configurations are available upon request.
Typical Applications:
  • Fiber coupled diode lasers
  • Couplers and pump combiners
  • Beam delivery cables
  • Spectroscopy and instrumentation
Features & Benefits:
  • Robust industry standard design for compatibility with most systems
  • Exceptional geometric uniformity and core/clad concentricity for ease of assembly
  • Clean room fiber draw to eliminate coating "hot spots"
  • Pure Silica Core for high resistance to optical damage
Optical Specifications:
