VersaLab Optix

VersaLab Optix Breadbord

Quantum Design introduces its first portable, cryogen-free cryocooler-based material characterization platform – VersaLab. With a temperature range of 50 – 400K, this 3 tesla platform is perfect for accomplishing many types of materials characterization in a limited space.

As with all Quantum Design instruments, VersaLab is a fully automated turnkey system with a user-friendly interface, and utilizes technology developed for Quantum Design’s popular Physical Property Measurement System (PPMS®). VersaLab is specifically designed for material characterization up to 3 tesla and over a wide temperature range without the need of liquid cryogens. Utilizing a new approach to cryocooler equipment design, VersaLab employs a new 4He-based temperature control system and gas flow technology that eliminates the need for liquid cryogens.

VersaLab Optix

The VersaLab Optix 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 ± 3 T. The optical breadboard allows a wide range of configurable experimental space seamlessly integrated onto the VersaLab Optix. 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. Optional laser light sources or 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 (5X magnification) controlled directly from the Multi-Vu software is 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.
