<p>PROBLEM TO BE SOLVED: To provide an optical microscope that provides high contrast of images, suppresses the leakage of light, and enables observation of light from a minute area while the light being distinguished from light from the adjacent area.SOLUTION: There is provided an optical microscope having a pupil filter. In the pupil filter, complex transmittance of the pupil surface of the optical microscope is a function of a radius r; an amplitude part is represented by a function obtained by multiplying the SINC function by the Hanning window function; and a phase part is constant or represented by a function obtained by approximating its amplitude part by a step function or a smooth function, and has the maximum in a peripheral part.</p> |
