WebDec 26, 2013 · The rule of thumb for useful magnification is around 50x per inch of aperture, but it depends on the target, type of scope, and other factors so it's a pretty soft rule. Think of it like magnifying a photo on your computer. You can zoom in to see more detail ... until you start seeing the pixels. WebHighest Magnification Levels Typically, the standard light microscope will max out at about 1,500X magnification and the electron microscope will be able to achieve 200,000X magnification. To put that into perspective the human eye can see things down to single strand of hair, the thickness of which is about 0.065 millimeters. snowman wax warmer plug in
