Abstract: An optical unit includes an input portion configured to have measurement light having a wavelength extending from an ultraviolet region to a visible region input thereto, an optical system configured to condense the measurement light in a state where a chromatic aberration is caused to occur, and an opening portion configured not to image light having a wavelength in the visible region and to image light having a wavelength in the ultraviolet region of the measurement light having a chromatic aberration having occurred therein.
