The highest-quality spectral data with a new, faster field spectrometer system

The FieldSpec 4 Hi-Res spectroradiometer has been designed for faster, more precise spectral data collection in remote sensing applications. The enhanced spectral resolution offered by the portable, ruggedized, high-resolution spectroradiometer is well suited to geologic applications and other fields of research that require definition of narrow spectral features, especially in the longer wavelengths.

  • Faster spectral collection speed by allowing researchers to measure more targets at more sites in a smaller timeframe.
  • The full-range (350 – 2500 nm) Vis/NIR FieldSpec 4 Hi-Res provides the highest spectral resolution available in a portable, ruggedized field spectroradiometer.
  • An extended wireless range presents new opportunities in research supervision from longer distances.
  • New ruggedized fiber optic cable and a smaller, lighter, yet tougher case make the FieldSpec 4 Hi-Res field ready and highly portable.

The FieldSpec 4 Hi-Res spectrometer has increased signal throughput, improved spectral resolution and vastly improved signal-to-noise ratio over previous ASD field spectrometers. For remote sensing, this means faster spectrum capture in the field with improved spectrum quality. Researchers looking at materials at longer wavelengths—such as carbonates, clays and chlorites—will benefit from a 2X radiometric performance increase in the SWIR 1 and 2 regions. The FieldSpec 4 Hi-Res spectrometer, with an 8 nm resolution, is also ideal for building spectral libraries, since it provides the high spectral resolution spectra required to support current and planned hyperspectral sensors.

Ideal for geologic applications requiring mapping of alteration mineralogy, the FieldSpec 4 Hi-Res spectroradiometer is also suited for hyperspectral image validation and ground truthing.

Unique Applications



Refernce 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. All reference panels and standards may be purchased separately.

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.

Fiber Checker Magnifiers

This ASD proprietary software and hardware diagnostic tool was developed so that people using ASD spectrometers can check the internal glass fibers built into the fiber optics. The Fiber Checker allows the user to reverse illuminate the VNIR, SWIR 1 and SWIR 2 regions individually or all together. By attaching the Optical Magnifier and counting the illuminated fibers, the user can then confirm that there are no broken fibers internally on the fiber optic cable.

Hi-Brite Muglight

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

Hi-Brite Contact Probe

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

Plant Probe & 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.

THE GPS RECEIVER (Optional)

The GPS receiver for the FieldSpec HandHeld 2 automatically provides geographic coordinates for each corresponding spectrum file.

go-Lab Mobil Çalışma İstasyonu

The goLab™ Mobile Work Station acts as a wheeled carrier for streamlined transport between locations, and then quickly unfolds to support all your sampling needs “right on the spot”. For use with ASD’s full-sized portable spectrometers and spectroradiometers.

External Light Source-ProLamp (Optional)

The ASD Pro Lamp is a 14.5 Volt 50 Watt Lamp that is tripod mountable and adapted especially for indoor lab diffuse reflectance measurements over the region 350 - 2500 nm.

Integrating Sphere

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.
