Headwall VNIR-SWIR

Headwall’s VNIR-SWIR imaging sensor leverages a patented aberration-corrected design that provides very high spectral and spatial resolution with stable measurement accuracy. With diffractive optics specifically designed and manufactured by Headwall, the dual hyperspectral sensors do not exhibit image aberrations such as stray light, optical distortions, or thermal instabilities. Along with aberration-corrected imaging, the Hyperspec VNIR-SWIR sensor package offers a wide field of view and high signal-to-noise (SNR) performance. Pixels from both sensors are co-aligned through software.

Headwall’s Hyperspec® VNIR-SWIR sensor provides image data across the broadband range of 400-2500nm, reducing processing times and yielding superior imaging performance. A CMOS FPA is used for the VNIR sensor while a cooled MCT array is used for the SWIR sensor. Inside the enclosure is a high-accuracy GPS/IMU plus the data storage and processing computer. Headwall’s VNIR-SWIR airborne sensor package measures approximately 10.7” x 8.2” x 6.5” in size (272mm x 208mm x 165mm) and weighs approximately 6.25 lb. (2.83 kg), making it suitable for aircraft and certain UAVs.
