WebAs a result magnification numbers and field of view are still the same as that original definition, regardless of the size of the monitor used. The average difference in magnification between an optical microscope and a digital microscope is about 40%. Thus the magnification number of a stereomicroscope is usually 40% less than the ... WebMay 4, 2024 · The average depth of field at certain magnifications and apertures is 3 to 5 microns at 4x magnification, 0.5 microns at a 0.8 numerical aperture, and 0.1 to 0.2 microns at a 1.47 numerical aperture. At this range, advanced auto-focus systems such as laser trackers are essential, since manual focusing is almost impossible to achieve.
