Overview

For mining exploration geologists, these improvements translate into faster data capture at exploration targets and drilling sites. The improved data quality provided by the ASD TerraSpec 4 Hi-Res mineral spectrometer also allows for accurate assessment of low-concentration and low-reflectance minerals, like iron-containing minerals such as serpentines and chlorites, which were previously difficult to measure. Benefits include:

  • Enhanced optical configuration provides more precise spectral results for superior spectrum clarity and definition.
  • Industry leading performance in the SWIR 1/SWIR 2 regions for unparalleled alteration mineral identification.
  • Standard ruggedized steel covered fiber optic cable ensures consistent spectral quality.
  • No need for sample prep, which means fast field scans.

Pair the ASD TerraSpec 4 Hi-Res mineral analyzer with The Spectral Geologist (TSG) software from Spectral Geoscience to analyze the spectra and produce mineralogical output products.

Probes and Lighting

Contact Probe

The ASD Contact Probe is designed for contact measurements of solid raw materials such as minerals, grains, other granular materials. Its innovative optical design minimizes measurement errors associated with stray light and allows for measurement of samples through clear and transparent plastic bags.

In addition to the standard contact probe, ASD also offer the Hi-Brite contact probe and the Plant Probe.

All contact probes are available with a ruggedized cable feed and cable, designed for applications that involve extra cold or harsh temperatures. (see image below specifications)

Specifications:

Length10" ( 25.4 cm)
Weight1.5 lbs (.7 kg)
Power requirements12-18 VDC, 6.5 W
Lightsource type/Life (approx.)Halogen bulb/1500 hours
Halogen bulb color temperature2900 K
Spot size10 mm

Fiber Optic Illuminator

The Fiber Optic Illuminator is a portable, external light source designed for use with ASD instruments and sampling accessories that do not have a built-in light source.

Technical Specifications

Length   11.43 cm (4.5 inches)
Width   8.255 cm (3.25 inches)
Weight   292 grams (10.3 ounces)

Muglight

The ASD Muglight is designed for analysis of raw materials requiring reflectance and absorbance measurements. It can measure samples through glass vials, or using the ASD sampling tray adapter. It's unique and innovative design minimizes measurement errors associated with stray light and specular reflected components.

For users requiring higher intensity illumination, ASD also offers the Hi-Brite Muglight.

Muglight specifications:

Rapid Analysis Probe

The Rapid Analysis Probe is specifically designed for speedy spectral collection of powders and other fine-grained materials such as small uniform seeds and grains. Its beveled tip and metal jacket greatly speed up the spectral collection process of fine grained materials to optimize workflow. Simply insert the Rapid Analysis Probe into your fine-grained media, collect the spectrum, use a chemical wipe to swipe the probe clean and move on to the next sample. It’s that easy! The Rapid Analysis Probe comes with a gimbaled white reference for high performance calibration. It can be used for quantitative predictive models.

If using this probe with a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is necessary. The Fiber Optic Illuminator provides the light source needed for sample collection.

Technical Specifications

Length: 21.6 cm (8.5 inches)
Spot size: 4 mm

Small Diameter Reflectance Probe

With an approximate spot size of only 2 mm, the Small Diameter Reflectance Probe was designed to collect spectra from individual small materials such as individual grains or vugs in a hand sample or rock core. It’s perfect for determining specific mineralogy of individual grains.

If using a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is required. The Fiber Optic Illuminator provides the necessary light source for sample collection.

Technical Specifications

Length: 10.2 cm (4 inches)
Field of View: 1 mm

Turntable

When your application requires analysis of irregularly shaped or non-homogeneous samples, the ASD Turntable is ideal for obtaining a highly accurate average. Especially useful for instrument owners in the grain, agriculture, pulp and paper, food, plastics and mining industries.

The Turntable offers:

  • 53.2 mm sampling spot size
  • Rotates at 22 RPM
  • Fits up to a 150mm sample dish
  • Compact (8"x11"x11" or 20.32 cm x 27.94 cm x 27.94 cm) footprint.

Have used this spectro-radiometers for over 20 years. TerraSpec 4 Hi-Res is a robust instrument, in terms of use in field and lab conditions. Easy to calibrate. Results are reliable. I will keep using this technology for many years to come. The instrument, if it's adequately treated, could last for ever. Very cost effective.
