The Vertical polarizer filter can bring you the sort of quality DLS performance you get with glass cuvettes while using low-cost plastic cuvettes – by reducing the scattering noise.

As an example of the effectiveness of this use of polarizers in DLS measurements, look at the graph to the side.
The Vertical Polarizer can also be used during NIBS measurements of concentrated samples to reduce multiple scattering making the measurements at higher concentrations more realistic. This approach was reported by Ragy Ragheb & Ulf Nobbman in Nature’s scientific reports 10, article 217168, 10 Dec 2020
Last but not least, by applying Horizontal Polarization you differentiate Rotational Diffusion from the classic Translational Diffusion we normally use to calculate particle size. This can help identify particles having a shape that is creating some slower than expected diffusion.
