Three thermal hyperspectral cameras in the LWIR region, 8 to 14 µm, have been specially designed to meet diverse requirements in industrial, research and security applications. Two models, HS and HR have uncooled detectors and optics and the C model with cooled detectors.

The HS model
Compact at a 3.5kg weight, the HS (High Sensitivity) model captures in the 8-12 µm spectral range. With 30 spectral bands and spectral sampling of 200 nm, good sensitivity and moderate spectral resolution, the HS is suitable for many industrial and chemical imaging applications.

The HD model
Also a compact 3.5 kg weight, the HR (High Resolution) captures in the 8-14 µm range and is designed for applications that require high spectral resolution. With spectral sampling of 70 nm and 85 bands, HR is a solution for applications where the targets emit at higher than normal ambient temperatures or where an IR source is used to illuminate the sample. Application examples include gas emission analysis and infrared Chemical Imaging.

The C model
For the most demanding ground-based remote sensing and security applications,the C model has a state-of-the-art temperature stabilized LWIR imaging spectrograph integrated with the
highest-sensitivity-cooled MCT detector. Spectral Camera LWIR C captures at 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.
