X2 Environmental Data Logger

Sequoia offers two instruments for this application. The LISST-200X and LISST-VSF. Respectively, these are for small-angle VSF and full-angle VSF with depolarization. Both measure beam attenuation.

The VSF can be thought of as composed of forward scattered (0-90°) and back scattered (90-180°) light, typically denoted bf and bb, respectively. Back scattering, bb, is of interest for scientists and practitioners concerned with ocean color studies and remote sensing. Sequoia offers the Hyper-bb for measuring bb for these applications.
