Measuring Diffuse Powders and Films With UV-VIS-NIR

Measuring scattering samples with UV-VIS-NIR can be challenging for basic instruments. These samples will have diffuse reflectance or transmission and less light hitting your detector.

In this presentation, we will discuss diffuse reflectance accessories (DRAs) for collecting all light in a measurement as well as Agilent's universal measurement accessory (UMA) for measuring the angular distribution of the reflected light.
