ASD FieldSpec 4 Standard-Res Spectroradiometer

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 TerraSpec, FieldSpec 4 Hi-Res and LabSpec Hi-Res spectrometers.

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.

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.

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 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.

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 TerraSpec, FieldSpec 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.

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

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.

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.
