Product description

An extended wideband fused coupler (EWOC) for use in optical coherence tomography (OCT) at 850, 1060 or 1310 nm, with a bandwidth of 100 nm. Fiber optic couplers are used to form the interferometer in OCT systems to generate depth information. Using our proprietary fused fiber technology, this coupler is designed for low loss and wide bandwidth operation.

The EWOC splits over an extended bandwidth and can be ordered to operate at any of the popular OCT wavelength bands (850 nm, 1060 nm, and 1310 nm). Our EWOC has been developed to provide market-leading performance for use in high-resolution OCT imaging systems employing next-generation wideband wavelength-swept sources.

Key features

  • Low loss
  • Extremely Wide bandwidth operation
  • High reliability
