Zusammenfassung:An ophthalmic laser treatment apparatus for irradiating a laser beam to a patient's eye, comprises: a delivery optical system for forming the laser beam emitted from a laser source into a plurality of spots on a target surface, the delivery optical system including: a diffraction optical element for dividing the laser beam incident thereon into a plurality of diffraction beams in a predetermined spot pattern; a first zoom optical system placed on a side closer to the laser source than the diffraction optical element, the first zoom optical system being configured to change a spot size without changing a spot interval on the target surface; and an objective lens.
