|---|---|
| Technology Overview | |
| Conventional Raman Microscope | Laser beam moves from upper left to lower right using stage movement (raster/table scanning) |
| RAMANwalk Innovation | Uses galvanic mirrors for much faster and smarter laser movement |
| Scanning Method | Novel random walk algorithm that actively searches for Raman signal based on chemical information |
| Signal Detection | Identifies Raman signal even in low visual contrast samples; checks surrounding areas when signal is found; rapidly moves to different areas when signal is not detected |
| Example 1: PMMA and Polystyrene Beads | |
| Sample Description | PMMA (purple) and Polystyrene (green) beads with similar visual appearance; PMMA particles slightly smaller |
| 40 Seconds | Rough details visible; first indication of sample composition |
| 3 Minutes | Finer details emerge; user can decide if full measurement is worthwhile |
| 27 Minutes | Complete Raman image at full resolution collected |
| Example 2: Sugar and PVA Contamination | |
| Sample Description | Sugar (yellow) and polyvinylacetate/PVA (blue); small pieces of PVA among larger pieces of sugar |
| Full Raman Image Time | Approximately 50 minutes |
| RAMANwalk Preview Time | Approximately 5 minutes to conclusively answer: “Is there PVA in my sample?” |
| Traditional Raster Scan | After 5 minutes: only 10% of total measurement complete with no PVA detected yet |
| Key Benefits | |
| Time Savings | Exceptionally quick Raman image previews; significant acceleration of routine analysis tasks |
| Optimal Use Cases | Quick analytical tasks with reduced depth of detail; selection of regions of interest for detailed Raman imaging; contamination detection |
| Efficiency Advantage | Up to 10x faster for contamination detection and sample screening compared to traditional raster scanning |
| Philosophy | Work smarter, not harder |
