Scanning Probe Microscope Ntegra Spectra
Product Features
- The universal PNL platform provides the possibility to integrate scanning confocal scheme in combination with regular AFM and spectrometer to detect Raman scattering spectrum. This spectra may then be interpreted into complex information concerning chemical composition of the object.
- Substantially extending optical microscope and AFM possibilities laser equipped system would be indispensable in environmental sciences, material sciences, living cell investigations.
