Tescan Column Modes - Resolution Mode In the Resolution mode the condenser lenses are controlled as a zoom condenser, the intermediate lens is off, and the objective lens projects the focused electron beam onto the specimen surface with the minimum spot size. Two computer automated algorithms can be used: OptiSpot allows fast and reproducible set up of the maximum probe current for each selected spot size (i.e. optimum angular aperture and, therefore, resolution). OptiMag automatically provides the optimum spot size for the chosen magnification. In practical terms, the end results are consistent, reproducible, high resolution and high S/N images, which can be achieved quickly and easily - whether you're an expert microscopist or just a novice.
