The New Standard in Field Spectroscopy

Ideally suited to meet the needs of today’s researcher, the FieldSpec®4 Standard-Res spectroradiometer offers ASD’s state-of-the-art remote sensing technology with dramatically improved speed, performance and portability over previous models. This full-range Vis/NIR (350-2500 nm) portable spectrometer features enhanced capabilities in the SWIR 1 and 2 regions, as well as double the signal-to-noise performance, allowing you to cover more ground without losing any data quality.

  • Improvements in the SWIR 1 and 2 regions allow researchers to cover twice the area in half the time as the FieldSpec 3.
  • New spectrometer configuration provides double the signal-to-noise ratio performanceas previous ASD portable spectrometers.
  • New ruggedized fiber optic cable and a compact, impact-resistant case make the FieldSpec 4 Standard-Res field ready and highly portable.

FieldSpec 4 Hi-Res ile jeolojik uzaktan algılama ve spektral veri toplama potansiyelinizi geliştirin.

The FieldSpec 4 Standard-Res, with a 10 nm resolution, comes in a mobile package with a small, lightweight, impact-resistant case and a convenient backpack travel cover. A new ruggedized cable protects the fiber optics, nearly eliminating fiber breakage. An expanded wireless range adds flexibility by helping users capture spectra farther from the instrument controller.

The FieldSpec 4 is ideal for a wide range of applications, including hyperspectral image interpretation, crops and soils research, and radiometric calibration.

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-Intensity 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-Intensity 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.
