housing is independent from the current stage of the thermo-electric cooling. A
Cool model does not necessarily have a two-stage TEC.

Neutralization of the temperature influence on page 190
for a detailed
explanation.
Passive camera cooling
The Goldeye TECless models provide no active temperature stabilization for the
sensor. These models are especially suitable for environments with a low and
stable ambient temperature, or in application scenarios where the influence of
temperature on image quality is limited, for example at low exposure times of less
than 10ms.
Heating functionality of the G/CL-008 models
The TEC1 element of a camera usually has only the ability to cool the sensor. In
addition to that, the heating functionality of the G/CL-008 models also enables the
TEC1 element to heat the sensor. This ability has the following advantages:
•
The camera can operate at a sensor temperature that is higher than the
ambient or case temperature.
•
When used for low-temperature applications, if the ambient temperature is far
below +20 °C, or if the default temperature setpoint has been set high above
the ambient temperature, the warm-up period is considerably shortened. Even
in ambient temperatures below 0 °C, the camera reaches a stable
temperature within one minute.
•
The heating capability prevents any variation of the sensitivity curve caused by
fluctuation of temperature.
Activating the heating functionality of the G-008
After activating the heating functionality of the G-008, switching down to a
setpoint below the selected setpoint is disabled. The ability to switch to a higher
setpoint depends on the
SensorTemperatureSetpointMode
feature:
•
if set to
Auto
, the G-008 can switch to a higher setpoint, if it exists.
•
if set to
Manual
, the G-008 cannot switch to any other setpoint.
To activate the heating functionality of the G-008, follow the steps below:
Step 1:
Set the
SensorTemperatureTargetSetpoint
feature to the desired
target setpoint.
Step 2:
Set the
SensorTemperatureControlMode
feature to
TemperatureControlTarget
.
