Raman-SPM/AFM combined systems
You can combine the power of inVia with scanning probe microscopes (SPMs and AFMs) to investigate the composition, structure and properties of materials at nanometre scales.
Choose the best systemThe inVia is incredibly flexible; Renishaw can directly couple it to a wide range of AFMs and SPMs from vendors such as:
Choose the best SPM/AFM for your needs.
Image: AFM topography image (A) and TERS image (B) of carbon nanotubes. The TERS image provides very high spatial resolution information on the distribution of functionalised tubes within the tube bundles.
TERS: tip-enhanced Raman scattering
Selected inVia-AFM systems can perform tip enhanced Raman scattering (TERS). This exciting technique uses a sharp plasmonic tip to obtain chemical information at the nanometre scale.
Renishaw's specially designed flexible coupling arm can be used to optically integrate inVia to SPM/AFMs. It uses mirrors to direct the light, providing a higher efficiency than fibre optic coupling. You can get your spectra faster, and with higher signal-to-noise.
Alignment is easy. All combined systems offer an inbuilt video with white light illumination so you can clearly see both the probe tip and the Raman laser spot together—critical for TERS work.
Same location, same time
You can have confidence in your data. You can simultaneously acquire Raman and AFM data from the same point on the sample without having to move it. This ensures that your data are consistent, even if your sample is changing with time.
One combined system
Analysis is co-localised; you don't have to move your sample between systems and then laboriously hunt to find the same point of interest.
Two users can operate the inVia and SPM/AFM independently and simultaneously, without any compromise in the performance of either. You have a Raman system, an SPM/AFM system and a combined Raman-SPM/AFM system.
