RAMANview

Overview

The Nanophoton RAMANview enables Raman imaging with an ultra-wide field with deeper depth of focus and longer working distance opening up new possibilities.

Applications

Some examples of applications for the Nanophoton RAMANview include:

  • Component distribution across a tablet for drug improvement
  • Components and compositional changes across mineralogical samples such as granite
  • Analysis of polymorphism e.g. of silicon carbide
  • Analysis of crystallinity of moulded plastics
  • Analysis of the crystallinity of diamond

Features

Features of the Nanophoton RAMANview system include:

  • Maximum view area of 2.5cm, compared to a conventional Raman with view size of 0.002cm
  • Depth of focus of 640µm, compared to just 1µm for a conventional Raman. This largely negates sample roughness and drift
  • Longer working distance of 7cm compared to 0.1cm for a conventional Raman allowing examination of samples with dents
