Thermoelectric modules protect CMOS sensors from excess heat
CMOS sensors convert photons to electrons for digital processing, but thermal noise can cause the sensors to lose image resolution when the temperature increases. To prevent this deterioration, high-temperature Peltier coolers can reduce the sensor’s temperature.
Laird Thermal Systems’ HiTemp ET Series thermoelectric modules feature 53 models offering a variety of heat pumping capacities, geometric form factors and input voltages. Enhanced Peltier module construction prevents copper diffusion and degradation in performance and maintains a high coefficient of performance (COP) allowing for maximum heat removal into the air.
Featuring active cooling for applications operating in temperatures ranging from 80 to 150 °C, the HiTemp ET Series has a cooling capacity of over 300 watts in a compact form factor. The HiTemp ET Series is designed for higher current and larger heat-pumping applications offering precise temperature control accuracy achieving ±0.01°C.
