Scanning Electron Microscope
A scanning electron microscope can provide a considerable amount of depth of field (greater than that of the SeeNano system) and very high quality black and white images.
The resolution capabilities of the SeeNano 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!
SeeNano 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
