Ultra stable closed-cycle optical cryostat
HILA Workstation from Montana Instruments
If you are looking for an optical cryostat with closed helium cycle that provides a mechanically highly stable sample stage, the HILA (High Inertia Low Acceleration) workstation is the optimal solution. The system features advanced vibration isolation consisting of a passively dampened platform with low natural frequency combined with a mass compensation technology for ultra sensitive measurements. The kinetic energy within the sample space is minimized.
|4 – 350 K temperature range|
|1 µG√Hz (1 – 100 Hz) accelerations|
|10 mK temperature stability (ptp)|
|8 optical ports|
|133 mm diameter breadboard platform|
An innovative inertial ballast stabilizes the sample platform without impacting thermal performance.
Advanced vibration isolation technology allows a wide range of sample masses to achieve optimally low accelerations, despite cabling or other connections to the sample.
An integrated cold circuit board gives users easy access to electrical connections right at their sample.
Various options for sample mounts and feedthroughs are available. The fully automated operation eliminates costly and time-consuming cryogenic pitfalls. Due to the Closed-cycle the system does not consume any helium.
The two mirrors of a cavity typically have a distance of a few nanometers. It is critical that this distance remains stable during a measurement. The mount of the mirrors is very sensitive to accelerations.
Scanning probe microscopy
The most SPM applications require the probe head to be in a very close distance to the sample. This distance needs to remain stable while the sample is scanned. This requires that the probe head and the sample are exposed low accelerations only.
