K549 Split Stirling 3/4W Micro Cooler

Model K549 IDA split Stirling rotary cryocooler was specially designed to meet the cooling demands of large format FPA detectors in military type gimbaled systems. This model is a member in RICOR’s rotary IDAs, it shares the same cold finger/dewar assembly as models K548/K508 integral Stirling rotary microcoolers. This cooler is based on the concept of direct detector mounting on the cooler cold finger - IDA.

The K549 is designed to meet requirements of compactness, low acoustic noise and low vibrations. It also offers longer operating life, hence reduced life cycle costs. This cooler contains an on-board temperature controller that excels in accurate temperature stability and minimal temperature drift.
