Montana CryoAdvance 50
A fully automated, closed-cycle optical cryostat designed for quantum discovery and cold science. It provides a low-vibration, variable-temperature environment (3.2K - 350K) for electrical and optical characterization without the need for liquid cryogens.
System Capabilities
The CryoAdvance 50 is a "sample-in-vacuum" system that eliminates the need for liquid helium, using a closed-cycle cryocooler to reach base temperatures. It is engineered for stability, maintaining temperature within 10 mK and limiting platform vibration to under 5 nm.
It features unobstructed optical access through five windows (4 side, 1 top), making it ideal for photoluminescence and spectroscopy alongside standard electrical transport measurements.
Operating Modes
Electrical Transport
DC and RF feedthroughs allow for Hall effect, I-V curves, and resistivity measurements.
Optical Spectroscopy
Radial and top windows enable laser illumination and imaging (e.g., Photoluminescence).
Quantum Characterization
Stable low-temp environment for testing quantum materials and nanostructures.
Automated Cycling
Galaxy software provides fully automated temperature setpoint control and monitoring.
