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.

Refractometers
-
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The refractive index of a certain sample varies for nearly all materials for different wavelengths. This dispersion relation is characteristic for every material. Temperature has a very important influence on the refractive index measurement. Therefore, the temperature of the prism & the temperature of the sample have to be controlled with high precision.

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.

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.

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.
