Calibir 640

Uncooled IR Camera/Core

Advanced features
Advanced performance

The Calibir™ 640 uncooled long wave infrared (LWIR) camera offers outstanding shutterless imaging performance and great flexibility in a very compact package. With a frontal form factor of 29mm x 29mm the camera can be integrated in tight spaces for compact solutions. The microbolometer-based platform covers wavelengths from 8-14 µm and offers a variety of lenses. With VGA resolution, standard GigE interface and state of the art on-board processing features serve a wide range of uncooled imaging applications in industrial settings.


Shutterless Operation

The Calibir camera requires no mechanical shutter for calibration, meaning instant image output and no interruption for recalibration. The image output of the Calibir camera remains stable across time and temperature range, freeing your application from the inconvenience, size, and additional complexity of mechanical shutters.

Wide Range of Lens Options

The Calibir 640 supports a variety of different lenses, ranging from 7.5 to 100 mm focal length. Any of the Calibir series products are supplied with lens of choice and fully calibrated over an operational range of -40 to 60 °C ambient temperature.

Adaptive Contrast Enhancement

The Calibir 640 features advanced image processing algorithms that adapt to the image content, optimizing contrast to show the finest details regardless of conditions or intra-scene variations. With no manual intervention required, the Calibir 640 delivers high quality images reliably, wherever and whenever you deploy it.

Export Controls

The Calibir 640 cameras are currently classified as a "Dual Use" item under Group 1 (1-6.A.3.B.4.B) of the Canada Export Control List and Category 6 (6.A.3.B.4) under the Wassennaar Arrangement on Export Control for Conventional Arms and Dual-Use Goods and Technologies. As such, the Camera is subject to export control – export authorization is required to export the Camera from Canada, whether on a permanent or temporary basis.
