New Measurement Services for Optical Fiber Analysis
With the IFA-100 Multiwavelength Refractive Index Profiler AMS Technologies can offer measurement services for product development, incoming inspection and forensic analysis on optical fibersMartinsried, )
Line plots and Tomography scans
The measurements can be taken in one dimension giving a line plot of the refractive index at any given cross section of the fiber. This measurement assumes the fiber to be symmetrical and symmetrical geometry is assumed for the computation of the refractive index profile. For the two dimensional measurements several lower dimensional projections are combined to form a full surface profile of the refractive index. This computer tomography based approach does not take assumptions for the fibers being symmetric.

Environmental Testing Solution
The interferometry measurement technique used in the setup does not require external calibration. Measurements can be done with fiber diameters from 40 to 400µm, measurement wavelength from 450 to 980nm. Fiber material can be silica glass, non-silica glass or plastic. The accuracy of index of refraction is +/- 0.0001, accuracy of stress measurement is +/- 5 MPa.
