Secure in Air appreciates the professional service, knowledge and advice of Xenics in implementing the Gobi camera in our project GeoCampro. Our client was more than satisfied with the results, looking for (thermal) defects in the railways.
A cooled thermal core is a camera engine that consists of:
Cooled MWIR cores consist typically of a MCT (Mercury Cadmium Telluride), InSb (Indium Antimonide) or T2SL (Type 2 – superlattice) detector, all operating in the 3 to 5 µm mid-wave thermal band.
Cooled LWIR cores are less common and more expensive. They consists typically of a MCT (Mercury Cadmium Telluride) or QWIP (Quantum Well Infrared Photodetector) operating in the 8 to 12 µm long wave thermal band.
MWIR & LWIR thermal imagers are used to detect heat sources (vehicles, people, …). Compared to uncooled thermal imagers, a cooled thermal camera offers better sensitivity (lower NETD), higher frame rates and smaller pixel pitches. Therefore, a cooled core will offer superior image quality and is better suited for long range imaging applications. On the downside, a cooled core will come at a significantly higher cost compared to an uncooled LWIR core.
Cooled thermal imaging cores are typically used with long focal length (zoom) lenses for long range security and night vision applications. The compact cooled thermal camera cores are ideal for gimbals, security and surveillance products and thermal weapon sights.
A cooled LWIR core offers advantages over a MWIR core for detecting relatively cool targets against a cold background.
We offer the XCO-640. This stirling cooled MWIR core is equipped with built-in image processing features. These features consist of autogain, automatic exposure control and contrast enhancement for excellent image quality. As our customers integrate the camera cores into their systems, we offer a variety of interfaces for an easy integration. Next to that our XCO-640 is equipped with long focal length (zoom) lenses for long range applications.
