The LISST-Floc measures scattering at extremely small angles - it covers the range of scattering angles from 0.016 - 3 degrees.  This can  be used to measure optical consequence of turbulence, besides particle dynamics.  As the LISST-FLOC relies on scattering a very narrow angles, laser beam alignment issues become much more critical and important than for the LISST-100X.

As a consequence of this, it is not recommended to use a LISST-FLOC for profiling measurements or at water depths larger than ~ 30-50m. It should ideally be deployed on a platform (mooring, tripod etc.).

The significantly larger size range is achieved by changes in the optics.  A longer focal length receiving lens is employed, and to deal with the intrinsically greater likelihood of small numer statistics of the largest particles, the diameter of the laser beam is expanded also.

A notable detail: due to the extra length required by the longer focal length of the receiving optics, the main instrument case does not have room for batteries. As such, a separate battery case is provided.

Data capacity, instrument programming, and data reduction are all identical to the LISST-100X.
