Example Samples… Materials Characterization Principles Of Transparent Specular Samples: Part 1: Pale Yellow Green Gel 22 Feb 202024 Feb 2020 Abstract: The methodologies employed for UV/Vis/NIR spectroscopic materials characterization will very much depend on the properties of the individual sample. The most common methods will use both a stand-alone instrument…
Materials Characterization… Measuring S and P Polarization Spectra With A UV/Vis/NIR Spectrophotometer 18 Feb 202018 Feb 2020 Abstract: Polarization measurements along with polarization spectra are important applications for the materials characterization application area. In this short post we will discuss the methods used for generating S, P,…
Basic Theory… Navigating The Instrumental Polarization Artifact: Two Samples That Polarize Light 17 Feb 2020 Abstract: Polarization measurements and polarization spectra are important applications for the materials characterization application area. Understanding the native polarization of a spectrophotometer’s light beam and how polarizing samples can interact…
Example Samples… How Integrating Sphere Size Influences Diffuse Transmission Spectra 14 Feb 202017 Feb 2020 Measuring Non-Liquid Samples Transmission measurements involve shining light on a sample and measuring the light transmitted through it. The transmitted light is generally classified in three categories itemized below. A…
Basic Theory… Spectrophotometer Energy, Instrument Polarization Artifact 14 Feb 202017 Feb 2020 Abstract: A UV-Vis-NIR spectrophotometer is a powerful tool for investigating absorbance, transmittance and reflectance characteristics of materials. Although we are accustomed to seeing extremely flat baselines in these spectrophotometers, thanks…
Materials Characterization… Diffuse Reflectance Measurements Of Textured Samples (Fabrics) 30 Sep 201914 Feb 2020 The Problem Solid samples in general can suffer from a considerable amount of surface non-homogeneity. Placement of textured samples, such as fabrics with a defined weave, can lead to differing…
Basic Theory Light: The Essence of Spectroscopy 29 Sep 201921 Feb 2020 Although light is generally said to be a wave, unlike the waves that occur at the surface of a body of water, it does not require a medium. As shown…
