neaSCOPE’s patented detection schemes provides modulation to the reference beam in addition to modulating the tip height and detects only the signal affected by both modulations. This acts as a filter that completely suppresses all s-SNOM backgrounds, resulting in artefact-free images suitable for quantitative analysis.
neaSCOPE patented detection completely suppresses background
Detection schemes that don’t suppress multiplicative background produce artifacts
neaSCOPE is the only commercial nanoscale microscope that:
- Implements pseudo-heterodyne detection for reproducible background-free nano-images
- Delivers publication-ready results without drift correction or post-processing.
