Stirling Cooled Detectors

InfraRed Associates, Inc. offers an additional cooling option for our Infrared Detectors.  Stirling Cycle Cooled Detectors are offered in three different design packages allowing operation down to 75K, when required.  This option eliminates the need for Liquid Nitrogen cooling and is ideal for remote or unattended operation.

 

K508 Integral Stirling Micro IDDCA

K561 Integral Stirling Low Power Micro IDCA

K549 Split Stirling Cryocooler

K508 Integral Stirling Micro IDDCA: The K508 Microcooler design model is solidly based on the concepts of direct detector mounting on the cooler's cold finger, and integral construction of cooler and dewar envelope. Operation of the integral Stirling microcooler, driven by a DC brushless motor, is clean, silent and highly reliable. Model K508 has been in service since 1994. This cooler is extensively used in many commercial instruments. The Micro IDCA model K508 contains an onboard temperature controller, which offers standby, remote shutdown and over-temperature /over-current protection options. By adopting various types of dewar envelopes, this microcooler can meet the cooling demands of most advanced IR detectors.
