    Spectroscopy

    Raman & 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.

    (Andor Shamrock 193i Spectrograph with
    Compact Imaging SpectrographiVac 316 CCD)

    Quantum Design now adds in-situ structural and chemical spectra analysis to PPMS materials characterisation measurements at low temperature and high magnetic fields. This ability answers a growing demand in the research community. Offering a wide range of modular interfaces that feature cage system couplers, Quantum Design offers endlessly configurable connections between the Compact Imaging Spectrograph and the PPMS Optical Multi-Function Probe (OMFP). The spectrograph's "wide aperture" slit opens the door to a single set up with the OMFP to image the sample, while also allowing spectral information collection through the same optical path from the microscope.

This is accomplished using a differential ratiometric capacitance bridge, operating at 2.340 kHz, which offers high sensitivity and dynamic range.

    Optics

    Optical Multi-Function Probe

    The newly designed Optical Multi-Function Probe (OMFP) offers unprecedented flexibility and versatility that allows you to conduct photonic, quantum optics and correlative microscopy experiments within the variable temperature and magnetic field environments of the PPMS, DynaCool and VersaLab. The OMFP probe features a room temperature “head” with multiple access ports and integrated optical breadboard for mounting optical components such as spherical and achromatic lenses, turning mirrors, filters, diffusers, beam splitters, prisms, waveplates, fibre bundles and electrical wiring. The open modular design of the probe head provides easy access to the axial ports and connectors which can be configured to route electrical, single fibres, fibre bundles and miniature waveguides to the sample space. In addition, a central optical access port allows free-beam optics experiments in the cryostat. A 0.5 in. standard optical thread mount makes aligning and focusing lens assemblies fast and easy.
