Optical Fiber Cable Testing Equipment
-
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

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.

Application Specific LC System
Reducing Sugar Analysis System
-
The Nexera reducing sugar analysis system uses Shimadzu’s unique post-column boric acid-arginine fluorescence derivatization method. Unlike the refractive index detectors and evaporative light scattering detectors (ELSD) commonly used for sugar analysis, this system reduces the effects of impurities and offers both high sensitivity and a wide dynamic range. As a result, sugars contained in samples can be analyzed simultaneously, without dilution even when there are significant concentration differences.

UV Index Measurement
-
The sglux UV-Index sensors measure the UVI with a worldwide unique low measurement uncertainty of less than 5 %. This makes our sensors compliant to the highest measurement precisions class one according the DIN/EN 5031-11, chapter 8. Since 2018 our product UV-Cosine_UVI (ERYCA) is appointed for public authority tasks: The German Federal Office for Radiation Protection (BfS) services 27 measurement points in Germany for public information of the daily UV-Index. Twenty of these points (Andernach, Chieming, Duderstadt, Fichtelberg, Genthin, Giessen-Wettenberg, Schauenburg-Kassel, Langen, Lueneburg, Munchen-Neuherberg, Norderney, Belm/Osnabrueck, Schauinsland, Tholey, Todendorf, Waldhof-Falkenstein, Waldmuenchen, Wurmberg, Zingst and Zirchow) use the sglux ERYCA to obtain the local UV-Index value. In 2017 ARPANSA (Australian Government’s primary authority on radiation protection and nuclear safety) began replacing the existing biometers with SiC photodiode UV sensors (sglux ERYCA) at all network sites. There are currently thirteen measurement sites in Australia that have been upgraded to the new sensors.
