ASD FieldSpec 4 Hi-Res NG Spectroradiometer

Higher resolution hyperspectral sensors yield greater precision for remote sensing classification applications, producing more information from every pixel generated in an image than ever before. To help maximize the full potential of these next generation sensors, measurements from ground based instrumentation need to meet or exceed the sensor’s spectral resolution. In the absence of this resolution equality, data is interpolated during post processing and vital spectral information can be smoothed and lost.

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

Hi-Brite Contact Probe

The same design, features, and benefits of ASD's standard contact probe, but with a higher intensity illumination setting on the sample window. This higher intensity illumination is ideal for inorganic applications, and is recommended for mineral and ore characterization in mining exploration and research applications using the TerraSpecFieldSpec 4 Hi-Res and LabSpec Hi-Res spectrometers.

Hi-Brite Muglight

The same design, features, and benefits of ASD's standard Muglight, but with a higher intensity illumination setting on the sample window. This higher intensity illumination is ideal for inorganic applications, and is recommended for use with the TerraSpecFieldSpec 4 Hi-Res, and LabSpec 4 Hi-Res spectrometer models.

The Hi-Brite 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.

Size5.5” x 3.7” (14cm x 9.4cm)
Weight2.91 lbs (1.3 kg)
Power requirementsInput power 5.5 W, bulb 4 W
Light source (type/life) approx.Tungsten Quartz Halogen b/1500rs
Bulb color temp2900 K
Spot size12 mm

Plant Probe

The same great design and functionality as ASD's standard contact probe with a lower intensity bulb position for non-destructive data collection from live vegetation and other heat-sensitive targets.

The plant probe can be used alone or in combination with a Leaf Clip to protect sensitive plants.

Leaf Clip Version 2

ASD's Leaf Clip assembly interfaces with the ASD Plant Probe. The Clip comes with the same replaceable white and black background standards (eight of each including the pre-mounted ones) that were included with the previous version of the leaf clip. 

The white backgrounds are .120mm thick x .935" OD Gore-Tex white PTFE reflector material. The black backgrounds are .004" thick x .935 OD black painted Vinyl. White Reference Cap (A122634) or 3.62” Spectralon (A128533) can be used as white background in addition to the Gortex for more accurate measurements. 

The Leaf Clip 2 also uses the same mounting bracket as the FieldSpec pistol grip, enabling it to be secured to the backpack waist belt when not in use.

Integrating Sphere

Integrating spheres collect reflected light from samples over a full hemisphere. The sphere, by nature of its internal diffuse (lambertian) reflection and integration of the energy, is insensitive to directional reflectance features coming from the sample, and therefore, gives a very repeatable “averaged” response to the reflectance of the sample placed in the beam at the sphere port. Sample placement and incidence beam/collection alignment are less critical to the measurement results because the integrating sphere looks at representative averaged energy from all angles at the same time.

General Accessories

Pistol Grips

ASD offers multiple pistol grip options for superior ease-of-use and adaptability to a variety of environmental and situational elements, when using your FieldSpec® and FieldSpec HandHeld instruments. All pistol grip designs include the quick-connect/disconnect fiber optic cable snap-in feature, pistol grip clip assembly for safely and securely affixing the pistol grip to your waist-belt on the back pack, and many offer a built-in bulls-eye level for added precision.

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.

FieldSpec Dual

Stop waiting for “ideal” weather to get your fieldwork done

The FieldSpec Dual collection software system leverages the value and utility of the world’s most trusted line of portable field spectrometers. The software intercalibrates and wirelessly synchronizes two ASD FieldSpec spectroradiometers to collect near simultaneous white reference and sample target radiance spectra. The system virtually eliminates errors associated with time varying atmospheric conditions, one of the biggest challenges to collecting accurate field spectra.
