Abstract: In a microscope having a plurality of optical units each including a filter block between an objective and a tube lens, the optical unit closest to the objective among the plurality of optical units includes a first filter block provided with an optical filter having a first effective diameter. The optical unit closest to the tube lens among the plurality of optical units includes a second filter block provided with an optical filter having a second effective diameter larger than the first effective diameter.
