STVP-100 Optical Cryostat

Janis

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" 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 (4) quartz window sets
• Optical sample holder
• Temperature sensor
• Pressure relief valve
• Sample positioner with one (1) 10-pin and one (1) 8-pin electrical feedthrough
• 6' superinsulated cryogen transfer line
• Control heater
• System test

Typical Applications

• Raman Spectroscopy
• UV, VlS, IR, FTIR
• Optoelectric Effect
• Photoluminescence
• High Tc
• Microscopy
