Microscope

摘要

A microscope has a plural number of objective lenses switchable from one to another, a memory circuit for storing parfocality data for the individual objective lenses, and a correcting device for correcting imaging conditions on the basis of the parfocality data for an objective lens currently used and another objective lens to be selected for microscopy. The microscope is capable of always providing favorably focused condition even when the objective lenses are switched from one to another for changing observation magnification levels.
