Innova-IRIS – Atomic Force Microscope

The publication record proves that an off-axis reflection geometry is the best solution for maximizing the light capture while fully accounting for tip-shadowing and polarization effects. The Innova-IRIS utilizes a novel optical architecture that accesses the tip-sample junction from the front side of the probe to provide an ideal optical path free of obstructions. The co-designed integration of the Bruker Innova sample-scanning AFM with the Renishaw inVia Micro-Raman System uniquely retains the optical “hot-spot” alignment during scanning to enable the stringent requirements for integrated TERS imaging. Tip integrity and positioning are preserved over the long signal integration times required for such sensitive research.
