Working Principles:
The ASD FieldSpec 4 standard res. (FS4) is a transportable battery powered spectrometer. It is designed for measurements either in the course of field campaigns or in the laboratory. The spectral range of this highly resolving device covers wavelengths between 350 and 2500nm, the sampling rate is 0.2 seconds per spectrum. Three different detectors facilitate the recording of the spectra: a silicon-photodiode-array composed of 512 elements for the VNIR (350-1000nm) and thermoelectrically cooled InGaAs-photodiodes (Indium, Gallium, Arsenid) for each the SWIR1 (1000-1800nm) and the SWIR2 (1800-2500nm). With a spectral resolution varying from 3nm in the very short and 10nm in the farer wavelengths, the device records spectra based on the information of 2151 bands.
