The performance and modularity of the witec360 Raman microscopes combined with advanced cryostat and nanopositioner technology, which puts experiments down to 1.8 K in high magnetic fields within easy reach. Solenoid magnets up to 12 T are available, as are vector magnets, using low vibration closed cycle attoDRY cryostats. Excitation runs from the visible to the NIR through cryogenic compatible high numerical aperture objectives, with polarisation control on both excitation and detection, and options for time correlated single photon counting and low wavenumber Raman detection.

Published by Oxford Instruments as the world's first fully integrated Raman imaging and scanning electron microscope, bringing every feature of a stand-alone SEM and of the confocal witec360 Raman microscope into one instrument. Switching between the Raman and SEM measurement positions is quick and the sample transfer between them is automated, so results correlate and images overlay directly. Diffraction limited lateral resolution is 200 to 300 nm, three dimensional images and depth profiles are supported, and an ultra-fast Raman imaging option brings integration time down to 0.76 ms per spectrum. A RISE-EDS configuration adds Raman-SEM-EDS in the same instrument.
A high end confocal Raman and photoluminescence microscope configured specifically for chemical imaging of semiconducting materials. Wafers up to 12 inch, that is 300 mm, are handled on a 300 by 350 mm scanning stage, and peak shifts below 0.01 cm-1 can be detected. Vibration damping, TrueSurface active focus stabilisation and fully automated microscope control are included, and various laser wavelengths are available.
A mobile confocal Raman system for the applications where the laboratory has to travel to the sample. The Raman probe is positioned flexibly in front of bulky, immovable or precious objects that cannot be transported to a microscope or that will not fit under one. The system ships in a flight case of roughly 100 by 60 by 60 cm, covers about 90 to 3500 cm-1 depending on excitation wavelength, and is offered with 532 nm, 633 nm or 785 nm lasers at output powers from 30 mW to more than 200 mW. Spatial resolution is diffraction limited and the system runs under Microsoft Windows 11.
