Abstract

An optical apparatus and a microscope are designed so that high resolution and a high sectioning effect are provided; a time for obtaining an output image can be reduced; it is possible to observe the interior of an object in which light is strongly scattered, without using the fluorescent pigment; resistance to vibration is strong and observations can be carried out with high resolution; and a lamination structure of an IC pattern configured on a semiconductor wafer can also be observed.
