When Do I Need a Polarizer on my UV-Vis-NIR?

Polarizers are a common accessory on UV-VIS-NIR spectrometers. Though not needed for every measurement, there are certain common experiments where it is important to have one.

We will discuss in this presentation how polarizers operate in the spectrometer and some examples of when they are needed for transmission and reflection spectroscopy.
