SD InSb, 38–875mm

38–875mm Long-Range Cooled Thermal Camera

This Mid-Wave Infrared (MWIR) thermal camera uses a 15μm InSb sensor with a high definition resolution of 640×480, detecting infrared wavelengths from 3,000nm–5,000nm where terrestrial temperature targets emit most of their infrared energy. Using real-time image enhancements and a very precise thermal sensitivity of 0.025°C, this system is capable of detecting vehicles up to 43km away*, with a horizontal field of view as small as 0.65°.

While thermal is a significant investment, its superior range and performance allows it to significantly outperform other solutions for detecting long-range threats, making it a viable option for many applications.

MWIR Cooled Thermal Imager 

This high sensitivity 15μm InSb cooled thermal sensor with a resolution of 640×480 and a cooler lifetime of 10,000 hours MTBF. The cooled sensor is able to detect differences in temperature as small as ±0.02°C, providing more detail for tracking of targets at extreme ranges in total darkness and through most obscurants.

Indium Antimonide Cooled Thermal Sensor

38–875mm Germanium Zoom Lens

The InSb thermal core is paired with a precision-engineered ƒ5.5 germanium zoom lens has a 23X optical zoom range from 38mm to 875mm. This allows for excellent long-range detection performance by offering anything from a 14° to 0.65° field of view, and a resolution of 1.4ppm at 43km. These lenses also feature auto focus capabilities, delivering crisp, clear images even when adjusting zoom, ensuring optimal performance and situational awareness in the wide field of view and crisp details in the narrow field of view.
