Light Source for Monitoring Stability of Radiometric Instruments
Solid-state light source stabilized with optical, electronic and thermal feedback. Especially suitable for HydroRads, but adaptable to other radiometric sensors.
Features
Compact head on flexible cable adapts to various sensors
Temperature-stabilized head contains LEDs and reference detector
Optical feedback stabilization
Independent control of multiple LEDs allows spectrum to be tailored to specific devices
Drastically smaller, lighter, easier than incandescent sources based on the SeaWiFS Quality Monitor*
Typical Use
Secure head to device under test (DUT), using an appropriate adapter
Turn on thermal control; wait for "stable" light to indicate head has warmed up
Turn on light output
Measure output of DUT
Record data for comparison with future SLS measurements.
Options
Select specific wavelengths of interest
Select output radiance level
Adapters for mating head to specific sensors/instruments
