Enhanced PbSe/PbS detector performance can be achieved by both cooling and temperature stabilization. The latest available Thermoelectric Coolers (TECs) provide that control with greater efficiency at lower operating power levels. Cooling PbSe/PbS detectors increases sensitivity and extends the peak wavelength response. These improved heat pumps achieve the same ΔT with less required cooler power.
Better feedback control of the TEC top stage maintains detector temperature stability. Combined with proper heat sink design and identifying the optimum operating temperature, these superior TECs help to provide the best possible detection in the mid-IR.
