Closed-cycle optical cryostat with breadboard

Cryostation s200 (Nanoscale Workstation) from Montana Instruments

The Cryostation s200 (Nanoscale Workstation) provides an entire cooled breadboard platform for configuring your experiment.

The cooled breadboard offers the freedom to integrate a sample with multiple probes, nanopositioners and free-space optics right onto the cold platform. In this way, the cold platform simply becomes an extension of the optical table.

Use any of the seven radial and one overhead port for optical access to the experiment. Overhead optical access can be configurated for low working distance imaging. The versatile and spacious design allows for multiple RF and DC electrical, fiber optic and gas tube feedthroughs to be incorporated and thermally lagged for ease of use and high performance.

  • Integrate components on interchangeable cold breadboards
  • 4.3 k base temperature with 20 mK stability
  • Breadboard with 12.5 mm grid of mounting holes
  • Seven locations for thermal lagging to radiation shield
  • Compatible with window options and sample mounts from the Cryostation

Further information

Experimental setup and room temperature measurements in the Cryostation s200 (Nanoscale Workstation) cryostat can be done with the sample area completely unobstructed. For lower or higher temperature measurements, a radiation and vacuum case can be set in place without disturbing the sample.

The cryostat sample mount incorporates custom filament-wound materials and an engineered platform which maximizes strength and compensates for thermal contraction. This provides a rigid connection to the optics table with little or no drift with each new setpoint.

Our cryostat provides both low temperatures and low vibrations. Peak-to-peak vibrations are less than 15 nm. This is achieved with a patent-pending design which maintains a typical base temperature of 4.3 K and a typical active load cooling power of 0.1 W at 5.3 K with all eight optical access windows in place.

Using patent-pending active and passive temperature stabilization, the Cryostation s200  achieves long- and short-term temperature stabilities of less than 20 mK peak-to-peak, even at temperatures below five K. The Nanoscale Workstation will automatically stabilize at the user-defined temperature setpoint.

A number of processes are automated by the cryostat including vacuum pumpout, cooldown, temperature stabilization at setpoint, warm-up, and purge with dry nitrogen to keep the system surfaces, sample and optics clean. Compressor parameters are automatically optimized to minimize cooldown time, conserve power and reduce wear on the system. Diagnostics and monitoring of many system components are automatically performed, making troubleshooting a more straight-forward process for the user or a trained technician who can be networked onto the system as long as an internet connection is provided to the Cryostation s200.

The Cryostation s200 is controlled with a Windows-based program running on a mini-notebook computer. Using OLE Automation, the Cryostation can be driven by another device using LabVIEW, for example, for total experiment automation. The system can also be monitored and controlled via any computer with internet access.

In addition to the two calibrated Cernox thermometers, which are provided in the sample area, corresponding to the platform and sample temperature, the system is provided with 29 electrical connections into the sample area and four blank base side panels for interfacing signals. Standard options are available for RF, DC, fiber or gas tubes.

The large cold breadboard may be configured with a 190 mm platform or a 130 mm platform with 25 mm radiation shield lagging band for flexible experiment setup.

The sample space has a cylindrical shape and is 195 mm in diameter and 71 mm tall.

The Nanoscale Workstation has seven radial plus one overhead port for optical access to the experiment. Corresponding radiation-blocking internal "cold windows" on the radiation shield are provided. Windows are AR coated fused silica standard, with other coatings and window material available. The top window may be either 50 mm precision window or a 190 mm view port.


Nonlinear optical material property Nonlinear optical material property studies for applications pertaining to low power, all optical circuits for information processing by developing a solid-state cavity-nonlinear-optical device. This research requires free-space optics to be laid out on the 4 K breadboard to make cavities, as there are long wavelengths used in this research.
Light matter interaction Light matter interaction studies utilizing fiber taper waveguide couplers. This research is undertaken to understand the interactions in solid state systems and extending this to quantum information processing applications.
Semiconductor quantum dot Semiconductor quantum dot research - coupling of a quantum dot to the resonance of cavities for generation of single photon sources.
Nitrogen-vacancy center Nitrogen-vacancy center research involves micromechanical resonators coupled to N-V centers where low vibration is important.
Nanoscale microscope The microscope is available in horizontal format in the Nanoscale Workstation. This provides simple integration into your in-plane optical setup. Remove the lid for easy sample access. There is ample room on the cold breadboard for free space optics, enabling transmission experiments and piezo interface control.
