Lake Shore Janis ST-500 Microscopy Cryostat

Continuous Flow Cryostat

The Lake Shore ST-500 continuous flow cryostat is specially designed for use in microscopy, imaging, and high spatial resolution photoluminescence. The combination of the low thermal-expansion support structure and internal vibration isolation results in nanometer-scale vibration and drift levels. The cryostat geometry offers a short working distance (for use with high magnification optics) and permits mounting on common microscope stages and translators.

A cryogen-free option for continuous flow cryostats

FEATURES

  • Low vibration — 15 nm
  • Options for UHV
  • Options for nano-positioning stages
  • Can be used both in transmission and reflection geometries
