ABSTRACT:
The invention provides a multiphoton-excitation-type examination apparatus that efficiently generates a multiphoton-excitation effect, that makes the measurement head compact, and that can be easily adjusted when the measurement head is replaced. The multiphoton-excitation-type examination apparatus comprises a laser light source that oscillates ultrashort pulsed laser light; an optical fiber that transmits the ultrashort pulsed laser light from the laser light source; a support member; a measurement head supported on the support member so as to be movable upwards and downwards and at an angle, and having an optical system that irradiates a specimen with the ultrashort pulsed laser light transmitted by the optical fiber that measures fluorescence or reflected light coming from the specimen; and a dispersion-compensating member, in the measurement head, that compensates for group velocity dispersion of the ultrashort pulsed laser light irradiated onto the specimen.
