概述
對于采礦勘探地質(zhì)學(xué)家而言，這些改進可轉(zhuǎn)化為在勘探目標(biāo)和鉆探現(xiàn)場更快地捕獲數(shù)據(jù)。 ASD TerraSpec? 4 Hi-Res 礦物光譜儀提供的更高數(shù)據(jù)質(zhì)量還有助于準(zhǔn)確評估低濃度和低反射率礦物，比如蛇紋石和綠泥石等以前難以測量的含鐵礦物。 優(yōu)點包括：
- 增強的光學(xué)配置可提供更精確的光譜結(jié)果，從而實現(xiàn)的光譜清晰度。
- 在 SWIR 1/SWIR 2 區(qū)域中擁有行業(yè)的性能，確保提供的蝕變礦物識別。
- 標(biāo)準(zhǔn)加固包鋼光纜可確保穩(wěn)定的光譜質(zhì)量。
- 無需樣品制備，這意味著可以在野外快速進行掃描。
將 ASD TerraSpec 4 Hi-Res 礦物分析儀與 Spectral Geoscience 提供的 The Spectral Geologist (TSG) 軟件搭配使用，可分析光譜并生成礦物學(xué)輸出結(jié)果。

ASD TerraSpec® 4 Hi-Res 礦物光譜儀
探頭和照明
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:
| Length | 10" ( 25.4 cm) |
| Weight | 1.5 lbs (.7 kg) |
| Power requirements | 12-18 VDC, 6.5 W |
| Lightsource type/Life (approx.) | Halogen bulb/1500 hours |
| Halogen bulb color temperature | 2900 K |
| Spot size | 10 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:
| Size | 5.5” x 3.7” (14cm x 9.4cm) |
| Weight | 2.91 lbs (1.3 kg) |
| Power requirements | Input power 5.5 W, bulb 4 W |
| Light source (type/life) approx. | Tungsten Quartz Halogen b/1500rs |
| Bulb color temp | 2900 K |

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.
The Turntable comes standard with a 4000 hour halogen light source and one standard 150 mm x 15 mm Petri dish.

Reference Panels
ASD carries a wide array of calibrated and non-calibrated diffuse white and gray reference panels in varying sizes (from 2 x 2 in. to 12 x 12 in. or 5.1 x 5.1 cm to 30.5 cm x 30.5 cm) and reflectance levels, including encapsulated gray scale (NIST/NRC traceable) wavelength and USP standards for USP 1119. Calibrated panels come with certificate and documentation showing standard deviation and reflectance factors.
All reference panels and standards may be purchased separately. To provide our customers with a more cost-effective approach, specific sizes or styles of reference panels are included in accessory bundles designed for maximum compatibility with a particular application.
Your ASD sales representative will be able to advise you on the best option(s) for your needs.
