Thermoelectric Cooler

Using a built-in thermoelectric cooler (TEC) to cool an array detector is an effective method to decrease dark current and noise, as well as to improve the detection limit and dynamic range.

Cooling the InGaAs array detector from an ambient temperature of 25 °C down to −10 °C by the TEC reduces the dark noise by 3.5 times and the dark current by 12.25 times. This enables the spectrometer to detect weaker optical signals and function at longer exposure times.
