steady state temperature. For Sp y d er 2, at an ambient temperature of 25 °C and with no
airflow , the camera takes 90 minutes to achieve steady state and 20 minutes to reach
within 10 °C of steady state. If your system cannot perform flat-field correction after
w arm-up consider the recommended methods of reducing dark current and overall
camera temperatures (see bel ow).
Reducing Dark Current
The Sp y d er 2 mechanicals hav e been opti mi zed to tr ansfer heat from the sensor to the
front plate. Therefore, to reduce dark current the front plate is the ideal place to mount
heat si nks.
The heat fins on Sp y d er 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
pl ate temper atur es. 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.
