Optical Cryostat for Cryogenic Spectroscopy

The ST-100 optical continuous flow cryostat from Janis Research has interchangeable windows, so that the material and geometry can be selected to allow excitation beams for spectroscopy to pass through, from far infrared through to gamma rays.

Key Features

The standard configuration of the ST-100 optical cryostat consists of:

  • Optical vacuum shroud
  • Optical sample holder
  • Optical radiation shield
  • System test
  • Temperature sensor
  • Four 1.625" clear view quartz windows
  • One 10-pin electrical feedthrough
  • Three blank feedthrough ports
  • 6' superinsulated cryogen transfer line


The main applications of the ST-100 optical cryostat are listed below:

  • Microscopy
  • Matrix isolation
  • Raman spectroscopy
  • UV, Vis, IR, FTIR spectroscopy
  • Optoelectric effect
  • High Tc
  • Photoluminescence
  • Microphotoluminescence.
