The integrating sphere accessory is the most frequently used accessory on UV/Vis/NIR instruments. With an integrating sphere, one can measure just about any sample type including, solids, liquids, gels, creams, films, particle suspensions, skin, and other biologicals. In addition, samples that are turbid, cloudy, semi-transparent, or opaque can be easily measured as well. Integrating spheres are the Swiss Army Knife of spectroscopy. The ability to understand the measurement techniques of spheres is key to the evaluation of spectrophotometric materials characterization data.

The most common question materials characterization spectroscopists ask themselves is, “How do I measure this sample?” They ponder this as they are looking some unusual sample, like a rock or even a cockroach. And yes, they can both be measured with an integrating sphere accessory!

This webcast will consist entirely of spectra from a series of example samples that cover the range of specular and diffuse reflectance/transmission characteristics. We will concentrate on the decision-making process of how to measure these different sample types with both the stand-alone instrument and integrating sphere accessary. Included will be a detailed discussion of how to evaluate spectral data from the various sphere measurement formats. This webinar will also cover all the basic measurement configurations of integrating spheres and how to properly evaluate the sample’s material properties from collected spectra.
