Sequoia Scientific


Hyper-Spectral Backscatter Instrument

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.

Available for rental directly from Sequoia – one (1) month minimum rental period.

What is included in the base price for the Hyper-bb?

The instrument itself, a 1 m communication & setup cable, power supply, ship case, instrument stands, and a manual.

External battery pack, calibration tank, and cable(s) > 1 m for real-time data is NOT included.

Can I rent the Hyper-bb?

Yes. Sequoia has a rental unit available. The minimum rental period is one (1) month and the first month’s rent must be prepaid in full before the instrument is delivered. Subsequent months are invoiced at net 30 days payment terms. User must pay for the return shipping to Sequoia, and insure the instrument for the full price for the duration of the rental period as well as the return shipping.

If you decide to purchase a new instrument within 90 days after the return of the rental unit you can apply 85% of what you already paid in rental fees towards the cost of the new instrument.
