Refractive Index Profile
-
Preform refractive index profile measurements are arguably the most critical process control measurement during the fiber manufacturing process. The data collected can be used to determine the transmission and geometric properties of the fibers before they are drawn and inform subsequent manufacturing steps. Photon Kinetics’ refractive index profilers are trusted worldwide by fiber manufacturers to optimize fiber yields and produce consistent products.

S14
-
The S14 Refractive Index Profiler complements optical fiber preform analysis measurements by providing highly accurate and precise characterization of the refractive index profile of drawn single-mode, multimode, and specialty fibers using the RNF (Refracted Near Field) technique. The S14 index profile data produces fiber geometry information directly. Manufacturers can also use S14 data for the prediction of fiber transmission parameters such as mode field diameter, cut-off wavelength, and chromatic dispersion.

Ellipsometry And Reflectometry Systems
-
Based on non-contact optical techniques, FilmTek tools simultaneously measure multiple-angle and multi-modal data to determine film thickness and refractive index. By measuring multiple angles of incidence, a wavelength shift is introduced between spectra collected at different angles. The wavelength shift between the spectra is only a function of the refractive index of the film and the angle difference between the spectra. By independently determining refractive index from a wavelength shift (as opposed to extracting index information from amplitude changes), FilmTek tools have best-in-class performance for film thickness and refractive index measurement. This level of performance allows FilmTek tools to address applications that otherwise may not be possible with more conventional ellipsometry or reflectometry methods.

Film Thickness Measurement
-
Film thickness measurement can be measured using a number of different techniques depending on the thickness and number of layers. In its simplest form a simple measurement can be made of a single layer with a reflective lower surface using interference fringes. For more complex materials with multiple layers interference measurement is still made, but the mathematical deconvolution becomes increasingly important as does the refractive index of each layer.
