Magnification On A Microscope Refers To The Amount Or Degree Of Visual Enlargement Of An Observed Object.
In a microscope, the focal length is measured as the distance between the top of the specimen and the instrument’s objective lens. Microscope magnification is the microscope’s ability to enlarge an image of an object through a series of lenses to a size multiple times larger than the actual size of the object. Magnification is measured by multiples, such as 2x, 4x and 10x, indicating that the object is enlarged to twice as big, four times as big or 10 times as big, respectively.
