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.
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.
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 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.
FieldSpec 3 Hi-Res Portable Spectroradiometer
The FieldSpec® 3 Hi-Res is ideally suited for mineralogy research, as well as other applications that require high spectral resolution in the Short Wave Infrared regions.
With the power and reliability of the standard FieldSpec® 3, the Hi-Res offers the added benefit of 8.5 nm resolution in the 1000-1800 nm range and 6.5 nm resolution in the 1800-2500 nm range.
Higher resolution in the SWIR1 and 2 regions for greater definition of hard-to-resolve features often found in minerals and soils!
