Control of the sensor temperature
Warm-up period
After switching on the camera, the TEC stabilizes the sensor temperature at the
default setpoint, if possible. Except for TECless models, optimal image quality is
reached within one minute.
Goldeye G/CL-008 models are also able to heat up the sensor to any temperature
within the operating temperature range.
A red flashing temperature status LED indicates the warm-up period.
A steady green temperature status LED indicates the
Stable
temperature state.
Temperature stabilization and active cooling
Temperature-stabilized Goldeye models are equipped with a single-stage
thermo-electric cooling (TEC1) to keep the sensor at a stable temperature that is as
low as possible.
The specially designed Goldeye housing dissipates the heat build-up inside the
camera and radiates the heat into the environment
The dual-stage thermo-electric cooling (TEC2) allows you to operate the sensor at
a temperature well below ambient temperature. This allows for keeping a higher
image quality even with longer exposure times. However, with low sensor
temperatures and a larger difference to ambient temperatures, condensation on
the sensor is likely to occur. To avoid condensation, every TEC2-cooled sensor is
placed inside a nitrogen-filled chamber.
Use a heat sink to reduce camera temperature
To improve the cooling capability of the Goldeye stabilized and TECless models, a
heat sink set is available that can be mounted to the camera by the customer. Up
to four heat sinks can be fitted to one camera.
The heat sink set is available from Allied Vision, product code 1068300.
Application note: Usage of Heat Sinks with Goldeye Cameras
This application note explains the handling of heat sinks with Goldeye cameras and
lists additional methods to improve camera cooling.
