The WITec alpha300 R is a preeminent confocal Raman microscope for the topographic and spectroscopic imaging of material and component surfaces. It has been successfully applied to:

  • polymers, fibers, thin films and coatings
  • wet biological and inorganic samples
  • low-dimensional materials such as graphene flack
  • electrically conducting and non-conducting materials, and semiconductors

Please contact Stefan Arzbacher for aspects concerning accelerated lifetime testing (Lab4ALT) and Matthias Domke for more general inquiries concerning the Raman microscopy.
