Chapter 1 Introduction
The TerraSpec spectrometer is a high-resolution instrument that measures the
visible near-infrared (VNIR) and short-wave infrared (SWIR) spectra for
geologic remote sensing and analysis.
The TerraSpec spectrometer is specially designed for mining and geology
applications. It is ideally suited for performing reflectance and transmittance
spectral measurements of rocks, minerals, and core samples. Its higher
resolution is optimized for identification of minerals associated with
economic ore deposits.
The ASD Accessories Guide contains an array of devices to extend the
application areas for the spectrometer, the Hi-Brite MugLite and Hi-Brite
Contact Probe are specifically designed to work with this high resolution
instrument.
The TerraSpec spectrometer is compact and field portable. It has a spectral
range of 350-2500 nm and rapid data collection (10 spectra per second).
While its most highly regarded features are performance and field-portability,
these instruments perform competitively in the laboratory as well.
Features and Advantages
Accurate and Precise - high resolution and superior repeatability of
results for better discrimination and analysis of materials.
Rugged and Transportable - Resistant to vibration and changes in
temperature or humidity.
Fast - 10 spectra per second data collection for the entire 350-2500 nm range.
»0.1 second scanning time provides an accurate average every second
» Users can quickly scan several areas when analyzing bulk samples.
» Rapid analysis allows screening all or most samples versus spot
checking.
Compatible - Works with off-the-shelf mineral spectrum analysis software
available from SII and chemometrics software (such as Grams™
PLS
plus/IQ and Unscrambler®).
