RISE – Raman-SEM Microscopes

Brochure

App Note

World's first fully integrated Raman Imaging and Scanning Electron Microscopes

RISE Microscopy is a novel correlative microscopy technique that combines SEM and confocal Raman Imaging. Through RISE Microscopy ultra-structural surface properties can be linked to molecular compound information.

The RISE Microscope combines all features of a stand-alone SEM and the confocal Raman imaging microscope alpha300 within one instrument:

Quick and convenient switching between Raman and SEM measurement
Automated sample transfer from one measuring position to the other
Integrated software interface for user-friendly measurement control
Correlation of the measurement results and image overlay
No compromise in SEM and Raman imaging capabilities

The RISE Technique

For RISE microscopy samples are automatically transferred from one measuring position to the other within the vacuum chamber of the SEM, streamlining the workflow and drastically improving the instrument's ease of use.

Application Examples

Raman-SEM image overlay of a hamster brain tissue sample. Color-coded Raman image parameters: Green: White brain matter; Red: Gray brain matter; 100 µm x 100 µm, 300 x 300 pixels = 90,000 spectra, 50 ms integration time per spectrum.

Raman-SEM image overlay of a GaAs semiconductor sample. Color-coded Raman image parameters: Yellow: Gold substrate; Red: GaAs; Blue: Residues from production; 50 µm x 50 µm, 300 x 300 pixels = 90,000 spectra, 34 ms integartion time per spectrum.

Raman-SEM image overlay of a PMMA-PS polymer blend- Color-coded Raman image parameters: Green: Polystyrene; Red: Polymethyl methacrylate.

RISE Microscopy and EDX analysis of a geological sample. Left: Overlaid SEM-EDX image: Three different element groups can be distinguished (Orange: Si, O; Purple: Si, Al, Fe, Ca; Green: Na). Middle: The Raman-SEM image overlay of the same sample area shows the distribution of the molecular compounds. Right: Corresponding Raman spectra.

RISE Key Features

Scanning Electron Microscopy:

Scanning Electron Microscopy features a variety of analysis techniques. With RISE, the chemistry of molecular compounds can be imaged additionally.

Confocal Raman Microscopy:

Confocal Raman Imaging with unprecedented performance in speed, sensitivity, and resolution
Hyperspectral image generation with the information of a complete Raman spectrum at every image pixel
Excellent diffraction limited lateral resolution of 200 - 300 nm
Outstanding depth resolution ideally suited for 3D image generation and depth profiles
Ultrahigh-throughput lens-based spectroscopic system for highest sensitivity and best performance in spectral resolution
Ultra-fast Raman imaging option with only 0.76 ms integration time per spectrum
Non-destructive imaging technique: no staining or fixation of the sample required
