Hyper-bb

Hyper-spectral backscatter instrument for ocean optics

Sequoia presents the world’s first commercially available hyperspectral backscatter instrument – Hyper-bb.

The Hyper-bb is a submersible single-angle backscattering instrument with configurable spectral channels. The primary measurement delivered by the Hyper-bb is spectral backscattering over the wavelength range 430 nm to 700 nm. In addition to measuring spectral backscattering, the Hyper-bb also has high-performance depth and temperature sensors. Data collected with the Hyper-bb is saved onboard the instrument in non-volatile microSD memory which can be later downloaded via the Hyper-bb software.

Sequoia will begin taking orders for Hyper-bb in Q4 2019, with first deliveries towards the end of Q1, 2020.
