Large core fiber

Step index glass clad fiber (multi-mode)

Features:

  • Finer optical permeation over a wide region (DUV~NIR)
  • Excellent performance in laser welding machines and in the laser surgery field where high power optical energy is required
  • High mechanical strength allows easy handling
  • Various terminal assemblies are available to suit customer specific requirements

Applications:

  • UV spot curing
  • High power laser optic transmission
  • Spectrum analyzer
  • Laser surgery
  • Temperature measurement
  • Ultra-violet light guiding
  • Fluorescent analysis
  • Light guiding illumination
