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.

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.

Particle Size Analyzers
-
Particle systems can be complex, but measuring them doesn’t have to be! Anton Paar offers two different technologies to characterize particles from the nanometer to the millimeter range. The Litesizer series employs light-scattering technology to determine not only particle size, but also zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions. The PSA series uses laser diffraction technology to measure the size of particles in both liquid dispersions and dry powders in the micro and millimeter range. Side by side they open up a wide range of possibilities for comprehensive particle characterization.

Fuzhou Zhongtuo Optoelectronic Co.,Ltd
Gem Tester Refractive index is one of most important optical parameter. Gloss of gem can be estimated by the parameter.The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its inherent refractive. Besides, index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative.

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.

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.
