Focal Plane Array (FPA) Detector	The camera uses a cryogenically cooled FPA quantum detector which counts incoming photons during the integration time. By using a global shutter, all pixels are sensitive during the same period of time. The FPA is mounted in an evacuated Dewar and is located behind a cooled radiation shield (“cold stop”).
Stirling Cooler	Coolers with different MTTF are available. In case of failure, IRCAM can replace the cooler in-house within a few working days.
Data Interface Camera Link	Camera Link is a well-established, stable and reliable interface between camera and computer (via framegrabber card). In “Medium” configuration, the interface uses two cables. Fiber-optic cables can be used to increase transmission length. Additional secondary data interfaces can be integrated.
Windowing Mode	In windowing mode, only a rectangular part of the image sensor is read out. Decreasing the vertical size results in a higher maximum frame rate.
Multiple Integration Time Mode	The camera can change the integration time from frame to frame. Up to 6 integration times can be pre-selected. The mode can be used to increase the camera´s dynamic range.
Image Meta Data	Every frame transmitted from the camera contains a lot of additional information which belongs to the image, like e.g. frame number, MIO signal status, operating hours, etc.
Custom Backpanel	Based on a modular concept, the camera backpanel is customized to support all available features and electrical interfaces of the camera.
Ventilation System	An active cooling system with integrated fans maintains the thermal drift on a low level, which is important for the measurement accuracy and permits to use the camera at elevated ambient temperatures.
Smart Lens Interface	Lenses are mounted with a square flange. The flange contains integrated electronics for storage of the lens ID and measure¬ment of the lens temperature. Camera and software automati¬cally recognize the lens and use the temperature information for thermal compensation. The lens is thermally isolated from the camera housing.

Data Interface Gigabit Ethernet	Connects to any PC via network interface card. Note: The maximum frame rate may be limited by the bandwidth.
Data Interface USB 3.0	Connects to any PC via USB 3.0. Optional: fiber-optic extension for long-distance transmission.
