Designed to meet existing and emerging challenges, cryoRaman offers excitation wavelengths from VIS to NIR with optimized spectrometers, 1.6K to 300K operating temperatures, high magnetic fields, patented cryogenic Raman-specific objectives and an exceptionally precise piezoelectric scan stage.

“We’ve seen interest in cryogenic Raman grow rapidly and expand beyond the initial core of graphene and carbon nanotube research groups,” said Florian Otto, Head of Business Sector Cryogenic Instruments at attocube. “We decided together with WITec to address the broadened user base’s increasingly varied experimental requirements. cryoRaman is the successful realization of that effort to redefine low-temperature chemical characterization in terms of user-friendliness, flexibility and outright capability.”

Research on phase-transitions and emergent properties of novel low-dimensional materials will benefit in particular from cryoRaman’s high magnetic field options. The solenoid or vector magnets, with a strength of up to 12T, are ideal for investigating transition metal dichalcogenides (TMDs) and van der Waals heterostructures, and can also help in determining the temperature- and magnetic field-dependence of photoluminescence. Optional modules include precise software-controlled laser power adjustment, multi-wavelength excitation capabilities, automated switching from optical microscopy to spectroscopic imaging, automated spectrometer calibration light source and routines, and time-correlated single photon counting (TCSPC) modes.

cryoRaman also introduces a pair of unique functionalities to cryogenic Raman microscopy: the ability to detect low-wavenumber Raman peaks, and full polarization control in excitation and detection. “Researchers looking at materials in cryogenic environments like to get as close as possible to the excitation wavelength, and they’re very interested in polarization measurements,” said Olaf Hollricher, Co-founder and Managing Director at WITec. “To meet those requirements, we developed features that have no equivalent in the marketplace. In fact, with its imaging capability at low temperatures, level of integration, performance and accessibility to both Raman newcomers and experts, cryoRaman is really in a class by itself.”

The close cooperation between attocube and WITec has produced an instrument ready for an unprecedented range of measurements. cryoRaman incorporates the very latest technology from two trailblazers in their respective fields to establish cryogenic Raman microscopy as a convenient, versatile and indispensable tool for materials scientists.
