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
