PPMS Features


PPMS Optix

High capacity dewar for PPMS with
Optix breadboard.


PPMS Optix is a flexible, modular optical platform that provides "turn-key" measurements and custom built experiments. It is the ideal platform for combining photonics, quantum electronics, optics with electro-transport, and magneto-optic materials characterization measurements at cryogenic temperatures and in magnetic fields of ± 16 T. The optical breadboard allows a wide range of configurable experimental space seamlessly integrated onto the PPMS. Various light sources, opto-mechanical and imaging components can be easily mounted and coupled to the cryogenic and magnetic field environment of the sample space. By integrating the Optix option onto a PPMS system, users can perform multiple measurements in a single sweep by combining Quantum Design's existing measurement options with new optical possibilities.

Optional laser light sources (such as Raman or a Xenon Arc lamp) are available for providing the necessary source for excitation beams for optical and spectroscopy experiments. An integrated compact imaging spectrograph and CCD camera controlled directly from the MultiVu system software are also available to automatically collect spectra and sample images as a function of temperature and magnetic field.

Raman & Luminescence Spectroscopy System

Raman and Luminescence Spectroscopy System

Quantum Design's new Spectroscopy System combines Raman and Photo-Luminescence spectroscopy with optical sample imaging in the variable temperature and magnetic field environment of the PPMS. Using this "turn-key" system, gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. Raman spectroscopy is a non-destructive spectroscopic technique used to identify and explore vibrational, rotational, and other excitation modes in a sample. Raman spectroscopy is commonly used to identify crystalline materials by measuring their specific Raman "fingerprint." This is done by measuring the inelastic scattering of light. In crystalline samples, the inelastic gain or loss of energy produces narrow discrete peaks known as Stokes and Anti-Stokes peaks, respectively. Glasses, in contrast, have broad vibrational spectra that in turn give rise to broad Raman spectra. When using the versatile PPMS Spectroscopy System, the study of spin-lattice coupling in strongly correlated oxides as a function of temperature and magnetic field is made easy through the highly automated MultiVu interface.
