Which FieldSpec spectrometer for me?

With such an extensive range of spectral resolution options in the SWIR range, and ultra-portable VNIR-only models, it can be hard to know which of ASD’s FieldSpec 4 spectrometers and spectroradiometers will best suit your specific application. That’s where we come in.

ASD pioneered the science of field spectroscopy over 25 years ago. With a strong commitment to R&D, ASD’s enhancements to core instrument spectrometers and other critical components have dramatically improved overall performance, signal, and integration speeds compared to earlier models. 


A spectrometer for every occasion

The ASD FieldSpec 4 leaves the factory floor calibrated as a spectroradiometer, ready for precise radiance and irradiance measurements, but is equally suited for use as a spectrometer for accurate contact or stand-off reflectance analysis with a wide range of standard accessories.

All ASD FieldSpec spectrometers and spectroradiometers provide 3 nm spectral resolution in the VNIR (350 nm – 1000 nm) range. Four spectral resolution options are available for the SWIR (1001 nm – 2500 nm) range.

  • The enhanced 6 nm SWIR spectral resolution of the ASD FieldSpec 4 Hi-Res NG spectroradiometer provides both the sampling interval (bandwidth) and the spectral resolution to support accurate calibration and image classification analysis with the next generation high spectral resolution hyperspectral sensors.
  • With 8 nm SWIR spectral resolution the ASD FieldSpec 4 Hi-Res spectroradiometer is the instrument of choice for geological studies and atmospheric research.
  • The ASD FieldSpec 4 Standard-Res spectroradiometer, with 10 nm SWIR resolution is perfectly suited for characterizing spectral features with a resolution of 10 nm to 50 nm, which covers the technical requirements of most field researchers. The ASD FieldSpec 4 Standard-Res spectroradiometer has long been the industry’s go-to workhorse instrument for trusted field spectroscopy and the scope of potential applications is broad.
  • Because of its wide optical slit the ASD FieldSpec 4 Wide–Res spectroradiometer provides the highest signal throughput and offers the best signal to noise performance of any ASD FieldSpec model. These high throughput characteristics also benefit field measurements taken in less than optimal illumination conditions. The 30 nm SWIR resolution of the ASD FieldSpec 4 Wide-Res spectroradiometer makes it an ideal fit for applications such as vegetation analysis and vegetation indices that are characterized by broad spectral features. This instrument is also available at a significantly lower price point than other ASD FieldSpec models, which makes it an attractive option when budgets are tight.

Not all research needs are created equal and the spectral reflectance characteristics of different materials can vary greatly. Portable Analytical Solutions has seen ASD FieldSpec 4 models applied in a huge variety of situations. Speak to us about your specific application goals.


Spectral Imaging Transforms Recycling

PAS brings spectral imaging to the growing recycling and waste management industry.

For the recycling industry, legacy ‘RGB’ technologies are unable to pick out the precise spectral characteristics that distinguish similar-looking types of plastic or paper products.

Although hyperspectral imaging sensors have been used for some time within the recycling industry, Headwall’s application-specific approach and a focus on robust, reliable instrumentation means that this technology is continually evolving and keeping page with the rapidly changing recycling landscape across the globe.

Headwall’s hyperspectral sensors collect image data across hundreds of spectral bands with exceptional resolution. The output of this process is a hyperspectral cube comprising all the spatial and spectral data within the field of view. When analyzed, the data leads to efficient, sensible, and profit-generating decisions.

Headwall’s fast-frame-rate Near-Infrared (NIR) Hyperspec® sensors cover the range of 900nm to 1700nm and are perfect for high-speed lines found within the recycling industry.

  • Compact, rugged design for durability and stability
  • Very wide field of view
  • 320 spatial bands and 166 spectral bands
  • Extremely high signal-to-noise

With this technology, the chemical composition of similar-looking materials is clearly distinguishable. Headwall’s Hyperspec III software not only controls sensor operation but integrates seamlessly with downstream robotics to complete the identification and sorting cycle.

Since recycling is a multi-billion-dollar industry, it pays to be precise. And Headwall is able to produce hyperspectral sensor solutions that allow you to achieve real competitive differentiation by extracting more value from your high-speed operation.
