Descripción del Producto

The high performance, cost effective spectroradiometer solution

A cost-effective solution for the analysis of any material with broad spectral features such a  general vegetation analysis and water column studies.

Because of its wider optical slit the FieldSpec Wide-Res field spectroradiometer delivers the best signal throughput of any FieldSpec spectroradiometer. High throughput benefits measurements taken in low illumination conditions.In addition to being a cost-effective field spectroradiometer, the FieldSpec 4 Wide-Res also functions well as a rugged, field 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

  • Plant Probe

For non-destructive contact measurements of live vegetation leaves and other heat sensitive targets.

Designed for use with the ASD FieldSpec® spectroradiometers for total hemispherical reflectance measurements of materials found in many optical remote sensing, oceanography, forestry, and plant physiology applications.

  • Reference Panels

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.
