Light Measurement

	HydroRad In-situ Hyperspectral Radiometers Self-contained multi-channel radiometers with many configuration options for environmental monitoring, ocean color remote sensing, and more. All models offer built-in intelligent data logging for autonomous or real-time operation, plus internal rechargeable batteries.
	WALRUS Hyperspectral Radiometer Buoy Available in various configurations for simultaneous measurement of up to 5 light quantities, above and below the water surface.
	SpectraDAS Spectrometer Controller / Logger Provides the data logging and system features of the HydroRad family, for applications that don't require a completely submersible system. For any application requiring automated or remote data collection, whether in the laboratory or the field. Can be equipped with submersible light collectors, and weatherproof housing options are available.
	Fiber-Optic Light Collectors Fiber optic heads that gather light for precise radiometric measurements by HydroRads or other instruments with fiber optic inputs
	SLS-1 Stable Light Source Solid-state light source stabilized with optical, electronic and thermal feedback, for monitoring the stability of HydroRads and other radiometric instruments.
	HydroShutter-HR Motorized copper shutter covers fiber optic light collectors between measurements to eliminate bio-fouling.
