Deep Ocean Laser Diffraction Particle Size Analyzer

The LISST-Deep instrument obtains in-situ measurements of particle size distribution, optical transmission, and the optical volume scattering function (VSF) at depths down to 3,000 meters.


The LISST-Deep extends operating depth range beyond the LISST-100X or LISST-200X instruments allowing measurements of particle size to be made with at 1 hz with minimal disturbance to the particles.
