SR-Series Laboratory Spectroradiometers
The SR-series are very high performance, laboratory spectroradiometers for the range from 280-2500nm. The all-solid-state design has no moving parts and features a silicon array (cooled and un-cooled options) for the UV-VIS-NIR band, with one or two TE-cooled InGaAs arrays for the SWIR band.
Choose Your Model
The SR-series comprises nine standard models which differ in terms of their wavelength range and resolution, based upon the number of SWIR cooled InGaAs array sensors fitted and the choice of a cooled or room-termperature silicon array sensor:
* The SR-3500 is available as a "remote sensing" value bundle, model RS-3500. The package includes DARWin SP software, a fibre with option of lens, radiance calibration, batteries, a hard case, a backpack, the Getac PDA, a reflectance standard and the pistol grip probe.
** The SR-1901 and SR-1901P are portable spectroradiometers intended for solar simulation application, and used for the test and classification of pulsed (PT version) and continuous solar simulators. They come with a NIST-traceable irradiance calibration. For pulsed measurements, the PT employs a separate photodiode which triggers the measurement.
The "signature" model is the SR-4500 which employs three, TE-cooled silicon and InGaAs arrays for a single broadband scan with the highest spectral resolution from 350-2500nm and the highest sensitivity of any comparable instrument. It is purpose-designed for spectral radiance calibration transfer with satellite imaging instrumentation. Reference users include leading NMIs and space institutes. A key feature is the very low (1%) drift from a cold start.
DARWin SP Software
DARWin SP spectral acquisition software is supplied as standard for data collection, averaging, storage and display of reflectance, radiance or irradiance spectra.
An accessory Getac remote control PDA is available. This is IP68-rated and uses the Windows Mobile OS which runs DARWin software. You can read the screen in direct sunlight. It has a built-in GPS sensor to geo tag each scan, a built-in camera and can take 20s voice memos. It has an 8 hour battery life. and is perfect for field use.
