Reducing Dark Current
The Piranha 2 mechanicals have been optimized to transfer heat from the sensor to the
front plate. Therefore, to reduce dark current the front plate is the ideal place to mount
heat sinks.
The heat fins on Piranha 2 improve conduction and provide a greater surface area for
convection (airflow). Mount fans away from the camera to avoid vibration, and direct the
airflow on the heat fins to decrease the temperature delta between ambient and front
plate temperatures. Convection is the ideal method to minimize camera warm -up times
and reduce dark current generation.
Both methods— either conduction through heat sinking, or convection through air flow —
greatly reduce dark current and will improve your system performance.
