Optical apparatus

A pattern irradiation apparatus includes a light source unit, an objective, a spatial light modulator, a light blocking member, and a control device. The objective irradiates a sample plane with light emitted from the light source unit. The spatial light modulator is of a phase modulation type and is arranged at a position conjugate with a pupil position of the objective and modulates a phase of the light emitted from the light source unit. The light blocking member is arranged in an optical path between the spatial light modulator and the objective and is configured to block 0-order light generated by the spatial light modulator. The control device makes a correspondence between a focusing position of the 0-order light generated by the spatial light modulator and a position of the light blocking member.
