Quantum Design OptiCool® Optical Cryostat

7 Tesla Magneto Optical Cryostat

The OptiCool by Quantum Design is a new magneto-optical cryostat using an innovative design that puts the sample volume in the heart of your optical environment. A custom 3.8 inch bore, split-coil, conical magnet offers fields perpendicular to the optical table up to ±7 tesla. The highly integrated design means, even with a magnet, your sample isn’t buried inside a large cryostat, far away from the optics. Seven side optical ports and one top optical port allow for optical access to your sample from a wide array of directions.

The OptiCool optical cryostat is a cryogen-free system with automated software to control temperature and magnetic field. At the push of a button you can change your sample temperature from 1.7 K to 350 K, with or without an applied magnetic field. A generous 89 mm diameter by 84 mm tall sample volume provides exciting possibilities in experiment design.

OptiCool’s Sample Pod provides a place to build and customize your experiment on the bench. When you are ready to make a measurement, the Sample Pod easily plugs into the pre-wired temperature control column. When your measurement is finished, the pod is easily swapped with another pod already wired up with your next experiment. The cryostat comes pre-wired with 16 wires, routed and thermally anchored from the outer User Wiring Ports to the sample volume. Additional wires can be installed for up to 80 wires total.

The OptiCool’s Sample Pod provides a place to build and customise your experiment on the bench. When you are ready to make a measurement, the Sample Pod easily plugs into the pre-wired temperature control column. Having multiple experiments arranged on multiple pods allows you to switch experimental hardware quickly. Sample Pods are available in both a standard configuration and a large-volume configuration depending on the experimental needs. Each type of pod can be further configured by changing the riser pieces (available in three lengths; included with the system) to adjust the height of the mounting plate.

Standard Sample Pod – Allows for mounting plate positions from 56.4 mm to 12.4 mm below the magnet centre.

Large-Volume Sample Pod – Allows for mounting plate positions from 131 mm below to 87 mm below the magnet centre.

The OptiCool can be custom configured with three different types of wiring assemblies. Each cryostat can have up to 5 wiring assemblies pre-installed. The wiring assemblies present the necessary connectors to make contact to the pod and take care of thermal lagging, necessary to reach base temperature.

  • Sample Wiring – Each sample wiring assembly contains eight twisted pairs for a total of 16 wires. Four 4-pin connectors are presented on the pod to make contact to your sample.
  • Positioner Wiring – The positioner wiring assembly is designed to be compatible with attocube piezo positioner stacks. Each assembly has enough wires to run up to 3 different axes of motion with the RES position feedback. If position feedback is not required, the feedback wires can be repurposed to run an additional 3 axes of motion. Contact Quantum Design for more information.
  • RF Coax Wiring – The RF coax wiring assembly contains four coaxial cables capable of carrying high frequency signals up to 20 GHz.
