Thicker films (>8um) produce a lot of optical fringes. A quick way to sort and measure such complicated spectra is to apply FFT. FILMeasure contains a suite of advanced tools to simply this analysis including: FFT Window Function, intelligent selection of wavelength range, and optical smoothing. We’ll also deal with the effects of measurement spot size and instrument selection. Multi-layered...

Let us consider the interaction of light source, spectrometer resolution, spot size, and numerical aperture of system optics as we attempt to measure films from angstroms to millimeters. It will be assumed for this webinar that the refractive indices are well established for the considered films. To finish off we’ll answer the very popular question: “how good does my GOF have to be?”

Traditional testing of laminate layers in a tire requires extensive dissection and can negatively impact the results. ProbeDMA™ eliminates the need to individually dissect the tire layers and allows the quantification of viscoelastic properties with high spatial resolution across layers and at interfaces. This session is a live demonstration of nanoindentation with the KLA nanoindenter to chara...

Polymers are exceptionally complex materials—mechanical properties depend on chemistry, processing, and thermo-mechanical history. Instrumented indentation testing dramatically simplifies the mechanical characterization of polymers, because samples can be small and minimally prepared. On bulk materials, values for storage and loss modulus measured by indentation agree well with values measured ...

Thin film layers control is extremely important to many technology-based industries. We will look by means of industry examples at two principal optical measurement types; spectral reflectometry and optical profilometry. The aim is to provide you with clarity into the physical working principles, when to use these techniques, and how to apply them to a variety of samples.
Thin-film interferenc...
