1.8 Thermal Considerations

The Osprey camera series has been thermally designed to separate the camera electronics from the image sensor.

The sensor temperature is thermally linked near the four M4 mounting holes on the face of the camera. Fairchild Imaging recommends mounting the camera using these holes to minimize sensor dark current artifacts.

Fairchild Imaging recommends that gain or offset corrections are completed after the camera has been turned on for at least 15 minutes. To do offset correction, cover the lens with your lens cap Follow this by removing the lens cap to complete a gain calibration. Make sure that gain calibration is completed with a uniform light source, illuminating the camera Field-Of-View (FOV).

Avoid excess ambient temperatures around the camera.
