ASD FieldSpec 4 Hi-Res NG Spectroradiometer
Manufacturer: Malvern Panalytical
Description
The ASD FieldSpec 4 Hi-Res NG spectroradiometer is a variant designed by Malvern Panalytical to provide enhanced spectral resolution, particularly in the shortwave infrared region. It measures spectra from 350 to 2500 nm, with a resolution of 3 nm at 700 nm and 6 nm at 1400 nm and 2100 nm. It uses a 512-element silicon array detector for the VNIR range (350-1000 nm) and thermoelectrically cooled graded index InGaAs photodiodes for the two SWIR channels (1001-1800 nm and 1801-2500 nm). The instrument is intended to support the calibration and validation of advanced hyperspectral imaging systems, offering a high density of measured wavelengths to capture subtle spectral details across its full operating range.
