The K508 microcooler design model is solidly

based on the concepts of direct detector

mounting on the cooler’s cold finger, and the

integral construction of the 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. Over

70,000 coolers have been fielded and

operate reliably onboard numerous ground,

airborne, heliborne, naval and space

applications. The 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.
