The high sensitivity of working parameters to temperature is the main feature of most photodetectors, so thermal management is one of the main tasks to ensure the operation of photodetectors. Thermoelectric modules feature compact design, high reliability and long service life, among other advantages. These advantages have also enabled them to be widely applied in the design of photodetectors.
Many detectors are required to be cooled to very low temperature such as -40C or -60C in order to have good detecting ability, we can provide multistage thermoelectric cooler for these applications.
