Description
The depth of field is the range of distances or thicknesses of an object that are simultaneously in good focus. The depth of field decreases as the distance from the object to the lens decreases. Thus, the depth of field for objects viewed with an optical microscope is very small. The depth of field increases with decreasing numerical aperture. The depth of field is frequently, but incorrectly, termed the depth of focus.
