Inside a Spectrometer - Light's Journey Through the Optical Bench

Dynamic Light Scattering (DLS) is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.
