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.

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.
A micro-Raman microscope for single spot analysis and mapping, engineered by Oxford Instruments for budget conscious customers who still hold high demands on instrument performance. It is built to be upgraded, so a laboratory can start at entry level and extend the system later.
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.
