Overview The results of many years of fundamental and experimental research have been condensed into the state of the art design of a very reliable miniature Stirling Cooler, combining two technical breakthroughs: flexure bearings and moving magnets. These two breakthroughs have resulted in an extremely reliable cryocooler, without sacrificing other important aspects such as affordability, compactness and weight. Main characteristics -Flexure-bearing suspension, -Moving magnet technology. -Wear is virtually zero. -2ndGeneration which is 33% smaller and lighter Our products 1STGENERATION – LSF 91XX FAMILY -LSF 9180 -LSF 9187 -LSF 9197 -LSF 9188 -LSF 9189 -LSF 9199 2NDGENERATION – LSF 95XX FAMILY -LSF 9580 -LSF 9587 -LSF 9597 -LSF 9588 -LSF 9589 -LSF 9599 LSF 93XX FAMILY -LSF 9320
