correlative microscopy
**Correlative Microscopy** is a **characterization approach that combines data from multiple microscopy techniques on the same sample region** — registering and overlaying information from different modalities (optical, electron, ion, scanning probe) to build a comprehensive understanding.
**Common Correlative Workflows**
- **SEM + EBSD + EDS**: Structure + crystal orientation + composition on the same area.
- **TEM + APT**: Atomic structure (TEM) + 3D composition (APT) of the same needle specimen.
- **Optical + SEM + FIB**: Defect localization (optical) → high-res imaging (SEM) → cross-section (FIB).
- **AFM + Raman**: Topography + chemical bonding on the same features.
**Why It Matters**
- **Complete Picture**: No single technique provides all information — correlative methods fill each other's gaps.
- **Registration**: Software tools (e.g., ZEISS Atlas) enable precise spatial correlation between datasets.
- **Failure Analysis**: Essential for complex failures requiring structural, chemical, and electrical information simultaneously.
**Correlative Microscopy** is **the power of many eyes** — combining complementary techniques on the same feature for a complete characterization picture.
