| Definition | A sensor system for measuring optical backscattering at 9 wavelengths between 412 - 715 nm. It uses nine LEDs (modulated at 1 kHz) for source light. The source light enters the water volume and scattered material is detected by a detector positioned where the acceptance angle forms a 117-degree intersection with the source beam. It contains three BB3 instruments and one data multiplexer (ECO Mux), all contained within a single pressure housing. Each BB3 instrument provides a backscatter measurement for three different wavelengths. It can include auxiliary sensors. Older versions could be fitted with an optional temperature and pressure sensor. Optical range is approx. 0.0024 - 5 m-1. | |
