| description | A focusing device that includes a differential interference prism used in differential interference observation in a focusing detection optical system includes: a light source that emits light with which a measurement surface of an observation sample is irradiated; a photo detection unit that detects light from the measurement surface; a focusing detection unit that detects an error signal near a focusing point of the measurement surface on the basis of an output signal from the photo detection unit; and a condition changing unit that changes an acquisition condition of the error signal. |
