How DuoScan works – the three modes
- Averaging mode
In averaging mode the laser spot is continuously scanned across a user-defined square surface
- Comparison between standard point measurement and DuoScanTM averaging mode with corresponding laser spot size and power densities on sample
2. Step-by-Step mode
In step-by-step mode a sample area is selected and the sample is scanned point by point across the chosen area.
- Mapping without moving the sample with 50 nm step size
3. Macro-mapping mode
Macro-mapping mode enables large sample surfaces to be raster-scanned to record an average spectrum across the whole surface, ideal for component distribution or to locate contaminents.
- Macro-mapping with full sample coverage using DuoScanTM with motorized stage
