STVP-100 Optical Cryostat

Optical continuous flow cryostats with three standard sizes available, although, as with all Janis systems, these systems can be customized to suit your experiment. Systems with a 1.5 in sample space are in stock for fast delivery.

Standard configuration

Designed for experiments requiring optical access to the sample, the Janis Research STVP-100 includes the following components:

  • Optical vacuum shroud
  • Optical radiation shield
  • Four quartz window sets
  • Optical sample holder
  • Temperature sensor
  • Pressure relief valve
  • Sample positioner with one 10-pin and one 8-pin electrical feedthrough
  • 6 ft superinsulated cryogen transfer line
  • Control heater
  • System test
