Uncooled LWIR camera for a range of applications

Calibir is an advanced camera platform with a small footprint (29mm x 29mm), featuring low power consumption, shutter-less operation and dynamic image enhancement. Calibir can be configured with a choice of (LWIR) lenses and output options to satisfy a range of applications including thermal night vision, perimeter and object security, search and rescue, firefighting and unmanned vehicle applications (e.g. robotics, UAVs).

The Calibir 640 features a 640x480 (VGA) resolution micobolometer to capture thermal IR images. Uncooled operation means that the camera corrects any temperature drift to which the detector is exposed and that no expensive external temperature stabilisation is required. This high resolution bolometer with small pixel pitch provides high responsivity to detect small remote objects. With its shutterless design, the camera offers rapid image output while delivering uniform response over the entire operating temperature range (-40°C to 60°C).

Shutterless operation and Adaptive Contrast Enhancement both contribute to imaging performance and to the ease of integration and use of the cameras. Adaptive contrast enhancement ensures that most information is always present in the image by automatically adjusting the contrast regardless of the temperature range in the scene.

The Calibir 640 series offers models with analogue or digital output formats. Analogue camera models are available with a BNC or a straight 10-pin connector - digital camera models support GigE Vision output. The analogue versions are well suited for defence applications which have an existing analogue infrastructure.

The camera is also available in a ‘Core’ version featuring a 60-pin Samtec connector which is intended for embedded system designs, in particular where the customer is responsible for the overall mechanical design of their devices. This camera core features user configurable parallel or serial digital interfaces, supports 8/14-pixel output and simplified serial commands.

The 11 LWIR lens options provide a horizontal field of view range from 6.2° to 90°. Calibir 640 Series models are sold pre-configured with a lens to ensure optimal response across the entire operating temperature range.
