The HR-1024 from the Spectra Vista Corp. (SVC) is their newest high performance single-beam field spectroradiometer measuring over the visible to short-wave infrared wavelength range (350-2500nm). The HR-1024 features include low noise indium gallium arsenide (InGaAs) photodiode arrays for the SWIR spectrum, higher resolution throughout, a robust compact light weight housing and wireless communication to laptop or PDA computers. The HR-1024 can be operated through a netbook computer in the field with full graphic, data storage and functional control. Three interchangeable fore optic lenses are included with the system together with a fibre optic light guide giving a wide range of fields of view.
