Abstract:
A laser treatment apparatus for irradiating a treatment part with a laser beam for treatment, the apparatus including:a treatment light irradiation unit including: a treatment light source which emits the treatment laser beam; an irradiation optical system which delivers the treatment laser beam; emitted from the light source to irradiate the treatment part, the irradiation optical system having a condensing lens which forms the treatment laser beam into a predetermined spot size on the treatment part and a scanning unit which scans the treatment laser beam two-dimensionally; and a laser emission end unit provided with the condensing lens and the scanning unit; a lens moving unit which moves the condensing lens in a direction of an optical axis; a movement unit which moves the emission end unit with respect to the treatment part, the movement unit including a first movement unit which moves the guide rail with respect to the treatment part relatively and an angle chance unit which changes an irradiation angle of the emission end unit; a determination unit which determined an irradiation position of the treatment laser beam; and a control section which transmits a control signal to the lens moving unit and the movement unit based on a determination result by the determination unit.
