Patent ID: 7176428

Claim:
A laser-based, multiphoton-excitation-type examination apparatus, comprising: 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, the optical fiber having a first end and a second end, the first end being connected to 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, the measurement head being connected to the second end of the optical fiber and incorporating an optical system that irradiates a specimen with the ultrashort pulsed laser light transmitted by the optical fiber and 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.
