Use of the NUC file reduces the maximum frame rate of the camera by an amount corresponding to
the impact of the NUC effort required. Typically this yields a 10-20% reduction in maximum frame
rate.
D.3.3.3 Temperature
The XEVA camera has a thermoelectric cooler that is used to stabilize the imager
temperature. The InGaAs imager is very sensitive to changes in temperature. To
ensure a stable image baseline the temperature should be set to a value below the
room temperature. Since 27°C is a nominal room temperature, and an operating
camera will warm somewhat above this, all TrueNUC files force a temperature value
of 17°C.
The camera has a cooler that can lower the imager temperature, but relies on normal
heating of the camera to raise it. The readout from the camera indicates that the
cooler is functioning and tracking to the target value. There is a nominal error
between the set and the reported value.
