Low-Vibration Temperature Control System
Ultra-low vibration sample chamber
The ultra-low vibration of the sample chamber is realized by the design of the vibration isolation structure between the chiller and the sample chamber on the air-float platform.
Installation base: Passive air-float platform
Minimum temperature: ≤3.0 K
Z-axis vibration: <100 nm
X/Y axis vibration: <100 nm
In order to meet the user's customized system requirements, FUTURE Quantum in the conventional cryogenic system based on the following additional types of upgrades can be provided, the order should be specified in advance.
01/ Precise temperature control
Through the combination of passive and active temperature control, we can realize the precise temperature control between 3K~60K.
