Hyperspectral Sensors
What Makes Us Stand Out
Headwall's HYPERSPEC® family of hyperspectral sensors and imaging systems are small, light, and rugged. The elegant all-concentric design uses precisely engineered master-quality holographic diffraction gratings made in our world-class cleanroom facilities to deliver outstanding signal-to-noise and spectral and spatial resolution, and a wide, aberration-corrected field of view.
Because airborne-acquired spectral data is influenced by several variables including atmospheric absorption and scattering, sensor-target-illumination geometry, sensor calibration, and image data processing procedures, Headwall offers radiometric calibration services.
Spectral Ranges
Our sensors operate across the 250 to 2500 nm wavelength range with the MWIR available upon request.
UV-VIS 250-500 nm
Biomedical, agricultural, and forensic applications can benefit from hyperspectral imaging in this wavelength range. Headwall offers a sensor with a uniquely ‘deep’ range down to 250 nm that may be paired with an illumination system.
VNIR 400-1000 nm
A number of Headwall sensors are optimized for the visible to near-infrared (VNIR) region of the spectrum. Remote-sensing and industrial applications benefit from rugged and notably small, compact, and lightweight systems such as the nest-generation Nano HP™ and the award-winning MV.X™.
Ext-VNIR 600-1700 nm
Extending the VNIR range to 1700 nm allows hyperspectral imaging for applications in remote sensing, industrial inspection, and chemical detection that need a longer reach into the near-infrared region while retaining some visible-wavelength capability.
NIR 900-1700 nm
Our Near-Infrared (NIR) wavelength range sensors are well-known for their outstanding performance for food-safety, material-sorting, chemical and pharmaceutical applications, and manufacturing inspection uses.
SWIR 900-2500 nm
We make both dedicated SWIR sensors for industrial inspection and grading, remote-sensing, and defense-security applications, as well as the next-generation Co-Aligned HP VNIR-SWIR sensor with industry-leading small size, light weight, and low power consumption for remote-sensing.
Lenses
Headwall offers a full selection of lenses for use within our wavelength ranges. Some of our sensors such as the award-winning Solar-Induced Fluorescence imaging sensor can be paired with a particular lens or set of lenses that result in optimized performance.

Data Acquisition Systems
Headwall can supply a data-acquisition system that provides the best fit for your chosen sensor. Our HyperCore provides Base CameraLink and Gigabit Ethernet and 470 GB solid-state storage in a rugged enclosure the size of a couple of packs of playing cards. Our High-Capacity Hyperspectral Data Processing Unit (HDPU) supports the full CameraLink (80-bit) interface, Gigabit Ethernet, full computer ports, and hot-swappable drives for large-data applications.
Pushbroom Scanning
HYPERSPEC® sensors are line-scanning hyperspectral cameras (sometimes called ‘pushbroom’ sensors) that collect reflected light through an image slit. One row of spatial pixels is collected per frame as the sensor or subject moves, with each pixel containing full spectral data. Motion can happen as a consequence of the platform (e.g., rotary or linear stage, UAV, aircraft, satellite) or the subject (e.g., food inspection line, conveyor belt). A hyperspectral data cube is created containing complete X, Y, and wavelength data that can be analyzed and managed through Headwall's or even third-party software.
