LWIR hyperspectral cameras are used in various applications including security, camouflage detection, and geological mapping. Two camera models are available – HS and OWL.
The LWIR High Sensitivity HS model has an uncooled bolometer FPA camera with a wavelength range of 8-12 μm, a moderate spectral resolution of 200 nm, and 30 spectral bands. It is a compact model that is appropriate for many industry applications.
The LWIR OWL model has a wavelength range of 8-12 μm and is an integration of a state-of-the-art temperature-stabilized imaging spectrograph and a cooled, highly sensitive MCT FPA detector. With a spectral resolution of 48 nm, 84 spectral bands, and an image rate of up to 100 Hz, the LWIR hyperspectral camera OWL model is ideal for the most challenging ground-based applications including remote sensing and security.
