Headwall Announces Compact, Co-Registered VNIR-SWIR Sensor Covering 400-2500nm
Responding to strong demand for a versatile wideband hyperspectral sensor covering from 400nm to 2500nm, Headwall has introduced its VNIR-SWIR sensor package that features co-registered pixels for outstanding spectral fidelity across the entire range. The package is light (less than 30 pounds [13.6kg]) and small (approximately 15” x 15” x 8” [381mm x 381mm x 203mm]) for use aboard a range of airborne platforms.
VNIR and SWIR pixel co-registration plus aberration-corrected optics yields very high spectral and spatial resolution with repeatable measurement accuracy. With diffractive optics specifically designed and manufactured by Headwall, the hyperspectral sensor contains no transmissive optical elements or prisms that contribute to image aberrations in the form of stray light and cross-talk. Adding to image quality is the sensor’s very wide field of view and high signal-to-noise (SNR). Headwall has accomplished this by combining the high diffraction efficiency for the VNIR and SWIR spectral regions coupled with very high quantum efficiency of the detector subsystems.
“Our remote-sensing customers often need to cover both the VNIR and SWIR range but don’t have the payload capacity to deploy two individual sensors and separate data systems,” said Headwall CEO David Bannon. “We developed this co-boresighted and co-registered VNIR-SWIR sensor to meet those needs affordably while keeping size and weight low.”
Headwall’s VNIR-SWIR sensor is available for delivery approximately 8 weeks after receipt of order.
