The Rook™ Cryogenic Nanopositioner


Product Name
The Rook™ Cryogenic Nanopositioner
Montana Instruments Corporation announces the upcoming Spring 2022 release of our brand-new cryogenic nanopositioner, The Rook™. The Rook™ has the lowest 3-axis vibrations to keep samples in focus, is fully integrated on all Montana Instruments configurable cryostats, and comes with best-in-class thermal links. Performance for The Rook™ is specified at the top of the 3-axis stack, providing the user with clear expectations of what is happening at the sample in terms of temperature, vibrations, and bi-directional run-out. Specifically designed for use in our CryoAdvance™ workhorse cryostat, it can also be utilized in the Cryostation® s200, our largest and most versatile closed-cycle cryostat.
