Featuring an axisymmetric design, the SymCool™ Free-Piston Stirling Cryocooler enables cylindrical modular integration with optical lenses, achieving significant space optimization and streamlined manufacturing. By coaxially aligning compression piston, expander, and adaptive damper, this architecture confines vibration vectors to a single degree of freedom, delivering ultra-low peak-to-peak displacement — redefining vibration suppression standards for demanding optical applications.
