AISAOWL
THE FIRST COMPACT HYPERSPECTRAL IMAGER FOR LWIR
SPECIM’s airborne thermal hyperspectral sensor AisaOWL, covers the contiguous spectral range from 7.7 to 12.3 µm in nearly hundred spectral bands. It has the sensitivity to detect and classify even gases. The AisaOWL is a fast pushbroom hyperspectral system designed to provide the remote sensing market with a high performance LWIR hyperspectral imager in the smallest achievable size. The AisaOWL has a built-in stirling cycle cooler, greatly reducing complexity and achieving compact size and low weight.
