Standard features
| 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. |
Optional interfaces
| Data Interface Gigabit Ethernet | Connects to any PC via network interface card. Note: The maximum frame rate may be limited by the bandwidth. |
