TerraSpec 4 Hi-Res Spectrometer
Manufacturer: Malvern Panalytical
SKU: TerraSpec 4 Hi-Res
Description
The TerraSpec 4 Hi-Res Spectrometer by Malvern Panalytical is a portable instrument for high-resolution spectral analysis, primarily used in mineral exploration and geological field studies. It captures data across a wide wavelength range from 350 to 2500 nanometers. The spectrometer achieves a resolution of 3 nm at 700 nm and 10 nm at 1400 nm and 2100 nm. Its detection system utilizes three separate detectors: a 512-element silicon array for the VNIR range (350-1000 nm), and two-stage thermoelectrically cooled graded index InGaAs photodiodes for the SWIR 1 (1001-1800 nm) and SWIR 2 (1801-2500 nm) ranges. This configuration yields high signal-to-noise ratios: 9000:1 at 700 nm, 9000:1 at 1400 nm, and 4000:1 at 2100 nm. The design emphasizes field durability and operational speed, often allowing for analysis without extensive sample preparation. Its enhanced performance in the SWIR regions supports the precise identification of alteration minerals.
