alpha300 R - confocal Raman imaging

alpha300 R – Confocal Raman Imaging

  • While long recognized as the state-of-the-art imaging system, ongoing development resulting from our innovative spirit keeps the WITec's Raman microscope alpha300 R at the forefront of the technology and sets the benchmark in terms of flexibility, sensitivity, speed and performance. These unique characteristics have established the alpha300 R the preeminent confocal Raman imaging system on the market.

    The flexibility of the alpha300 R series allows the system to adapt to all requirements, combine different imaging techniques and to evolve to meet new or expanded needs.
