0.48 NA Step-Index Multimode Fibers




  • Broad UV/VIS/NIR Spectral Range:
  • Reduced Static Fatigue
  • Lower Microbend Losses

 

Features

  • Broad UV/VIS/NIR Spectral Range:
    • 300 to 1200 nm (High OH)
    • 400 to 2200 nm (Low OH)
  • Reduced Static Fatigue, Lower Microbend Losses
  • Biocompatible Materials, Radiation Resistance
  • Sterilizable by ETO and Other Methods

Our 0.48 NA polymer-clad fibers offer high numerical apertures to suit a broad range of applications, from remote illumination to photodynamic therapy.

The cladding material utilized to achieve the large NA of these fibers is a softer polymer than normally found in polymer clad step-index multimode fibers. Consequently, the cladding material has a higher probability of being removed from the fiber when the buffer is being stripped for normal connectorization. The difference between the indices of refraction of the core and the cladding determine the NA. Thus, without the cladding, the performance of this fiber is greatly diminished. To combat this problem, Thorlabs terminates to the buffer instead of terminating to the cladding. That is, the connector is epoxied directly onto the fiber buffer, thereby eliminating the need to strip the buffer, and the cladding, off of the fiber. The image in the upper right corner shows this difference.
