| Definition | A cosine-collector underwater radiometer with a spectral range of 100-850nm and a depth rating of 200m. Scan speed ranges from 20-45nm per second at intervals of 1, 2, 5 or 10nm. The instrument combines a holographic rating monochromator, and order sorting filter wheel and a silicon detector, and all operations are controlled by an internal microcomputer. Spectral data are automatically corrected for the wavelength-dependent immersion effect. Scanning can be initiated from the surface or the insturment can be programmed for autonomous operation, so it is useful for both real time profiling and time series monitoring applications. Although the LI-1800UW is designed for underwater measurements, it is also calibrated for use as a terrestrial spectro-radiometer and can be used in air with the standard 1800 cosine collector or with any of the optical receptors available for the LI-1800 Portable Spectroradiometer. | ||
