Descripción del Producto

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

For non-destructive contact measurements and characterization of mineral and ore samples.

Designed for analysis of raw materials requiring reflectance and absorbance measurements of minerals and some inorganic material applications requiring a higher intensity light.

  • Fore Optics:

Foreoptics control the field-of-view and maximize data collection to better meet specific application requirements. A wide selection of foreoptics lenses are available for use with the FieldSpec® 3 and FieldSpec® HandHeld 2 spectroradiometer systems.Ideal for analysis of grain, food, and other irregularly or non-homogeneous material samples.

  • Leaf Clip:

Use with ASD’s family of Contact Probes for non-destructive, one-handed functionality, and improved analysis of live vegetation and other thin heat sensitive targets

  • Reference Panel:

Reference panels are available in calibrated and non-calibrated diffuse white and gray, in varying sizes and reflectance levels, including encapsulated gray scale (NIST/NRC traceable) wavelength and USP standards for USP 1119.
