OWL Thermal Hyperspectral Camera

Specim’s LWIR OWL is designed for the most demanding ground-based remote sensing and securit applications. Specim has integrated a state-of-the-art temperature stabilized LWIR imaging spectrograph with the highest sensitivity cooled MCT detector. Spectral Camera OWL covers the spectral range of 8 to 12 µm with high spectral selectivity of 84 bands (sampling of 48 nm) and extensive speed of up to 100 images per second.

Both of Specim’s LWIR spectral cameras are push-broom type line scan cameras that provide full, contiguous hyperspectral data for each pixel along the imaged line.
