Xem thêmThe RISE Microscope combines all features of a stand-alone SEM and the confocal Raman imaging microscope alpha300 within one instrument:
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.
Scanning Electron Microscopy features a variety of analysis techniques. With RISE, the chemistry of molecular compounds can be imaged additionally.
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.
