Quantum Design OptiCool® Optical Cryostat
OptiCool® and OptiCool® Vector 7 Tesla Magneto Optical Cryostat
The cryogen-free OptiCool platform leverages Quantum Design’s 40+ years’ experience in engineering and manufacturing automated temperature and magnetic field control systems. With fully automated cooldown and seamless temperature control through the range of 350 K to 1.7 K, the OptiCool platform also has the low vibration and stability that is critical to optical measurements. OptiCool’s innovative sample pod technology and generous 89 mm diameter by 84 mm tall sample volume provide exciting possibilities in experiment design allowing researchers to create and build customised set-ups for optical measurements. Systems feature a top window and multiple side window options to customise your optical access, including an option for a bottom window.
The standard OptiCool features a 7-tesla split-conical magnet with field perpendicular to the table and large volume of field uniformity, ±0.3% over a 3 cm diameter spherical volume. Its 7 side windows allow for unprecedented optical axis to a large experimental volume with uniform field.
The OptiCool Vector provides a magnetic field up to ±4 T perpendicular to the optical table and ±1 T in the plane parallel to the optical table. The four side windows in the X and Y axes of the magnet allow for transmission and reflection experiments in-plane parallel to the table. The top and optional bottom window in the Z direction allow for reflection or transmission experiments perpendicular to the optical table. The magnet power supplies in the OptiCool Vector allow users to precisely set the magnetic field direction relative to their sample and optical systems.

Testimonials
“Integrating the OptiCool® into my research program will allow for accessing experimental phase space in complex materials that simply wasn’t available to my group in the past. Innovative products advance science and the OptiCool certainly meets this standard.”
Prof. Richard Averitt of the Physics Department at the University of California San Diego
“A lot of my research over the years has been in the far infrared or terahertz. And so I think that the OptiCool® provides a really exciting opportunity to do novel far infrared spectroscopy on materials in a magnetic field environment.”
Prof. Richard Averitt, UC San Diego
