Product description

The go-to standard for trusted portable field spectroscopy

Ideal for characterizing spectral features with a resolution of 10 nm to 50 nm. The FieldSpec 4 Standard-Res is well positioned to meet a majority of the technical needs of field researchers who require dependable and trusted results from a field portable spectroradiometer.

It is the right choice for a wide range of remote sensing applications, including multispectral sensor ground truthing and calibration, agricultural analysis, and snow and ice studies. In addition to being a world class spectroradiometer, the FieldSpec 4 Standard-Res is equally suited to serve as a rugged, portable spectrometer for accurate contact reflectance or non-solar stand-off measurements.

Accesories

Contact Probe:

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.

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

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.

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 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.

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.

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.

Leaf Clip:

ASD’s Leaf Clip assembly is designed specifically for use with the Plant Probe to simplify the process of collecting spectra on live vegetation. The unique design includes a gentle trigger lock/release gripping system for holding the target sample in place without removing the leaf from its habitat, or inflicting damage.

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.

Pistol Grip:

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.
