S14 Refractive Index Profiler
The ultimate diagnostic tool for optical fiber production
The S14 Refractive Index Profiler provides accurate, precise characterization of the refractive index
profile of single-mode, multimode, and specialty fibers using the RNF (Refracted Near Field) technique. Fiber geometry parameters
and mode field diameter at user-specified wavelengths can be calculated from the S14 index profile data. Manufacturers can also
use the data to predict other fiber transmission parameters such as cut-off wavelength and chromatic dispersion.
Features and Benefits
- Fast automatic fiber location
- High speed sample scanning
- Index profile, geometry, numerical aperture and mode field diameter
- Calibration traceable to NPL
- Multiple reuse of measurement cells
