Description

The UP-LS series offers a comprehensive and versatile range of Linear Stirling coolers especially designed for cooling detectors in thermal imagers and IR sensors. Several of these cooler types are standard equipped with a patented thermal transfer block (Heatstop) in the cold finger, which reduces the required heatsink capacity at the warm end of the cold finger. The linear compressors can all be combined with several free displacer cold fingers.

The UP7097 is equipped with a displacer designed to fit into a 1/4″ IDCA dewar bore, and is available with several compressor types. The information listed above pertains to the version with 44 mm compressor and 60 Hz drive frequency, please contact us for information on other variants.

The manufacturing of the clearance seal bearings of our split Stirling coolers is performed in-house with an accuracy of 1 µm or less over the full length of the bearing. This very accurate initial match between piston and liner adds significantly to the cooling efficiency, while improving the production reproducibility and cooler.
