Temperature Stabilization of Uncooled Detectors
The uncooled infrared sensor is a thermal detector that can operate at an elevated temperature without the need for temperature reduction to enhance its responsiveness, detection and other radiometric characteristics. These detectors use materials that can operate at or above room temperature without degradation. The detector senses a change in conductance or some other temperature-dependent parameter and must be temperature-stabilized at or near the selected operating temperature to achieve optimal performance. Depending on the ambient temperature, the thermoelectric cooler either heats or cools the sensor to the desired operating temperature.
II-VI Marlow provides both stand-alone thermoelectric coolers and thermoelectric coolers integrated with a ceramic package where the package serves both as the bottom ceramic to the TE cooler as well as the base of the hermetic package for these applications.
