text: Light microscopes can show a useful magnification only up to 1000-2000 times.
text: A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×.
text: The 10x magnification is useful for micro soldering work – there is adequate room for the soldering iron between the eyepiece and the board – while the 20x for inspection.
text: Some stereo microscopes can deliver a useful magnification up to 100×, comparable to a 10× objective and 10× eyepiece in a normal compound microscope, although the magnification is often much lower.
