Cryogenic systems

PHOTEC provides comprehensive low-temperature solutions for customers, including low-temperature cryostats from 0.3 k to 4.2 k, low-temperature thermometers and controllers,  RF coaxial cables and low noise amplifers. We also provide deep customization services, including sample stage design, low-temperature motion and control, low-temperature optical systems, etc. 
  • By adopting a combination of passive and active temperature control methods, precise temperature control requirements between 3K and 60K are achieved

    Accurate temperature control
  • A shielding cavity is made of special permalloy that maintains high permeability at low temperatures, achieving magnetic shielding effect inside the cavity.
