Great equipment. Needs more diverse applications from scientists
Application Area: optics, photonics
"This is a wonderful equipment. You may not also use it for Raman imaging but much more than that. It is compact and easy to use. Witec values its customer very much and takes care of them. However, the application scientist should also need broader knowledge of the applications."

Robust and reliable instrument
Application Area:Ceramics, nanomaterials, polymers, carbon materials
"Hazzle free instrument. User friendly and could get reliable and reproducible results. I would give 5 star rating."

If you think of confocal Raman imaging microscopy think of the alpha300 R.
Application Area:Environmental samples
"Confocal Raman imaging microscopy is not a "press-one-button" technique for hasty end users. This applies as well for the WITec alpha300 R. It is a scientific instrument allowing state-of-the-art, spatially and temporally highly resolved Raman analyses. Anyhow, the high quality of the hardware components, and the well thought out software make working with that microscope a successful and satisfying endeavor. Not least it's the high quality support that makes the difference. The WITec people do not only know their instruments but also know how to use them with all kinds of samples. So in the end the new user will be able to optimize the system for the specific tasks and analyses to reach best possible results with reasonable efforts."
The WITec alpha300 R leads the industry in speed, sensitivity and resolution. These attributes are available simultaneously and without compromise. Speed is provided by the precise mechanical components and cutting-edge electronics, sensitivity is delivered through the optimized optics and detectors, and the exceptional resolution derives from WITec’s inherently confocal architecture and the know-how accumulated in almost 20 years at the very forefront of Raman imaging.
Chemical characterization of the individual components within a sample volume is a standard mode, but the accompanying WITec Suite data acquisition software can also visualize material properties such as stress fields or crystallinity. Time-resolved investigations of fast dynamic processes can also benefit from the ultrafast spectral acquisition times.
Confocal Raman imaging microscopes are among the most powerful and versatile instruments available to today’s scientists and no other product line places the full potential of the technique into the hands of users the way WITec’s alpha300 R can. It can be configured as required by a specialized experiment, or it can upgraded as requirements and techniques evolve. It features rock-solid stability, the freedom of modularity, and a level of performance only available from the preeminent Raman imaging manufacturer, WITec.
TrueSurface – For rough, inclined or irregularly-shaped samples. This module enables topographic Raman imaging, which keeps the surface, or a set distance below the surface, in constant focus during the measurement with little, if any, sample preparation.
TruePower – For setting the excitation laser power in absolute 0.1mW steps, with closed-loop monitoring and effortless documentation. This is not a relative power determination as is often the case with neutral density filter-based attenuators, but a real, useful and reproducible experimental parameter controlled through the same software as all other settings.
