witec360 Raman Imaging Mikroskop

Take your research in any direction with the new benchmark for Raman imaging

The Oxford Instruments witec360 is a unique confocal Raman microscope capable of routinely performing 3D chemical Raman imaging while maintaining the highest measurement speed and spectral quality. This is particularly beneficial for applications in which the exact spatial representation of the chemical components on the surface or within the sample is important. Depth profiles, 3D image stacks or topographic Raman images can be easily created with maximum informational content. The local resolution is always dependent on the physical diffraction limit and has an approximate minimum of 200 nm. At the same time, high-speed measurements are possible in which up to 1300 spectra per second can be recorded.

With the most recent release of the new witec360 Raman microscope Oxford Instruments takes imaging automation to the next level. It offers eease-of-use and ultimate capability by automating hardware control and offering pre-configured measurement routines. This streamlines the experimental workflow and yields reproducible results with unrivaled speed, sensitivity and resolution.

A critical advantage of Oxford Instruments Raman technology is the flexible, high-throughput Hexalight Spectrometer. It is optimized for the a full broadband excitation wavelength range. As a result the user achieves a much higher throughput than with conventional spectrometers and can operate, for example, with a lower laser power, which is of particular benefit when investigating sensitive samples.

If the laser power is to be accurately measured and adjusted, the customer can be provided with the TruePower option, which can be used to determine the absolute laser power in increments of 0.1 mW. The values ​​are recorded with the Raman data acquisition and can be retrieved later – important for internal documentation. The experiment can, of course, be repeated at a later time under precisely the same conditions.

Due to a modular design Raman microscopy can be correlated with AFM, SNOM or optical profilometry. With RISE microscopy, even correlative Raman-SEM images are possible.

The witec360 Raman imaging system offers several advantages for versatile research and development applications, without compromise in confocality while maintaining the highest spectral performance and speed and providing detailed 3D analyses of different samples. Straightforward operation is ensured by new innovative operating concepts. Raman imaging is therefore a flexible and versatile tool for chemical imaging and analysis.
