    Cryostation s50

    The Cryostation s50 is Montana Instrument’s flagship optical cryostat.  It combines low vibrations, stable thermal performance, optical access and a modular sample space configuration. The wide temperature range of 3.2-350 K enables a variety of experiments, whilst fast cool-down/warm-up times allow users to complete multiple measurements in a single day. There are a number of DC connectors installed as standard, and there exists many options for routing other signals into the cold space, such as RF coaxial wires, gas tubes and optical fibres.

     

    Features:

    3.2-350 K temperature range

    < 5 nm vibrations (pk-pk)

    < 10 mK temperature stability (pk-pk)

    ~ 2 hour cool-down time (to 4.2 K)

    150 mW cooling power at 4.2 K

    5 optical ports (x4 radial, x1 axial)

    CryoStation s100

    The Cryostation s100 system utilises the same patented vibration isolation architecture and proprietary thermal design of the Cryostation s50 instrument but provides over x2 the working sample space volume. The Cryostation s100 also incorporates a modular cold circuit board, which solves many of the common wiring challenges in a cryogenic environment. This is achieved via interchangeable platform "wedges" that make the system more robust, customisable, and simple to setup. 

     

    Features:

    3.2-350 K temperature range

    < 10 nm vibrations (pk-pk)

    < 10 mK temperature stability (pk-pk)

    ~ 3 hour cool-down time (to 4.2 K)

    Cryostation s200

    The Cryostation s200 uses the same back-end as the other cryostat platforms but offers the key advantage of a much larger sample space. This is realised with an integrated cold (4 K) breadboard of either 130 mm or 190 mm in diameter. This vastly increased sample volume allows a multitude of configurations and the ability to incorporate several components at one time – for example - multiple independent nanopositioner stacks, or multiple samples or integrated RF or optical probes.

    Cryostation s50 Vertical Cryo-Optic

    The Cryostation s50 Vertical Cryo-Optic Microscope integrates a high performance, colour corrected, vented objective into the sample space of the Cryostation s50 system for high NA imaging at low temperatures.  The vertical mounting scheme was primarily designed for confocal microscopy, with side optical access available to allow users to see the sample and approximate focus distance. The objective is temperature stabilised near room temperature and is supported via a dedicated UPS unit. The system includes XYZ low temperature nanopositioners for sample movement and focus adjustment. Additionally, if rapid change of the sample temperature is desired, the Agile Temperature Sample Mount is recommended

    Alternatively, it is possible to adapt the Cryo-Optic for use in the Nanoscale Workstation NW2 system – the difference being that the objective is orientated in the horizontal direction.

     

    Features:

    3.7-350 K temperature range

    < 10 mK temperature stability (pk-pk)

    Vertical (axial) objective

    Integrated XYZ low-temperature nanopositioners

    ~ 6 hour cool-down time (to 4.2 K)

    Choice of either 0.9, 0.85 or 0.75 NA objective

    x2 interface side panels

     

    Applications:

    Confocal microscopy

    Diamond NV centres

    Photoluminescence

    Low temperature Raman spectroscopy

    Cryostation s100 Horizontal Cryo-Optic

    The Cryostation s100 Horizontal Cryo-Optic is the latest model in the Cryo-Optic product line. This system integrates a high performance, colour corrected, vented objective into the sample space of the Cryostation s100 system for high NA imaging at low temperatures.  The horizontal mounting scheme provides seamless integration with other optical components – as well as particularly lending itself towards high NA transmission setups. As with the Cryostation s50 Vertical Cryo-Optic microscope, the objective is temperature stabilised near room temperature and is supported via a dedicated UPS unit.

    The system includes XYZ low temperature nanopositioners for sample movement and focus adjustment. Additionally, if rapid change of the sample temperature is required, the Agile Temperature Sample Mount is recommended

    HILA s200

    The HILA (High Inertia Low Acceleration) s200 workstation was designed to provide an ultra-stable mechanical environment for cryogenic measurements.  The system leverages a multi-stage active and passive vibration damping technique to isolate the cryogenic environment from both the vibrations of the cryostat itself and other sources of motion within a common lab environment. Energy within the sample space is minimised, creating the ideal environment for sensitive SPM, AFM or resonant cavity applications.

     

    Features:

    4.5-350 K temperature range

    Vibration isolated (‘floating’) cold platform

    Tuneable for a range of masses

    0.6 Hz resonance frequency

    < 20 mK temperature stability (pk-pk)

    ~ 8 hour cool-down time (4.5 K)

     

    Applications:

    Scanning probe microscopy (SPM)

    Cavity experiments

    Fibre-coupled microresonantors

    Magneto Optic

    The Magneto-Optic module integrates an electromagnet into the sample chamber of the Cryostation s50 system. This can be used to generate a magnetic field of between 0.5 and 1 Tesla (depending on the spacing between the pole tips). The magnet pole tips replace two of the standard radial windows however optical axis in this plane is maintained via 6 mm bore holes.  The top optical access port can be configured with a recessed objective for low working distance applications. An adjustable radiation shield accommodates unique experimental setups, allowing users to expand or resize the sample space or make adjustments to allow for more optical access options.  

     

    Features:

    3.4-350 K temperature range

    < 10 mK temperature stability (pk-pk)

    ~ 3 hour cool-down time (to 4.2 K)

    Bipolar field control

    0.5-1.0 Tesla magnetic field strength (dependent on pole spacing)

    Includes Hall Probe calibration sensor

    Includes magnet PSU and water-cooling

     

    Applications:

    Magnetic-optic Kerr Effect (MOKE)

    Spintronics

    Optical Magnetometry

    CryoFMR

    The CryoFMR is a FMR spectrometer from NanoOsc. When combined with the Cryostation C2 system and Magneto-Optic module, it can be used as a turn-key variable temperature Coplanar Waveguide Ferromagnetic Resonance (CPW-FMR) spectrometer. CPW-FMR is a spectroscopic technique that measures the coupling between an RF signal traveling in a coplanar waveguide and the oscillating magnetisation of a sample.  In turn, this can be used to determine the saturation magnetisation (Ms) or the gyromagnetic ratio (λ), in addition to parameters of the dynamic behaviour of the spin excitation, such as the intrinsic damping (α) and the inhomogeneous line broadening (ΔHo).  No Vector Network Analyser is required as the system uses an AC a lock-in technique.

     

    Features:

    10-350 K temperature range

    2-17 GHz frequency range

    AC field modulation via Helmholtz coils

    Includes Hall sensor assembly

    Coplanar waveguide with coaxial cables

     

    Applications:

    Coplanar Waveguide Ferromagnetic Resonance (CPW-FMR)
