Ergonom versus Scanning Electron Microscope
Comparison
Scanning Electron Microscope
A scanning electron microscope can provide a considerable amount of depth of field (greater than that of the Ergonom system) and very high quality black and white images.
The resolution capabilities of the Ergonom microscopes reach into the realms of mid-range SEM while offering a number of advantages:
- No sputter coating or staining required
- No vacuum required, viewed in normal room conditions
- Sample does not need to be cut to a small size to fit in a chamber
- Non destructive for living organisms
- SEM images are made at 45° angle causing image distortion!
- Ergonom images can be made at any angle between 45-90°
- Measerable in X, Y and Z axis
- Natural colors and grayfield contrast provide more image information
- Confocal imaging allows viewing below the surface of tissue samples
