摘要： PROBLEM TO BE SOLVED: To provide an automatic focusing mechanism capable of reducing the dependency of patterns formed in a samples to be inspected and to provide an optical image acquisition apparatus provided with the same.
SOLUTION: In the automatic focusing mechanism, a sample to be inspected 10 in which a pattern is formed is mounted to a mounting part 12, and a pattern-formed surface of the sample to be inspected 10 is irradiated with a light beam for observation which has passed through a slit 20 formed in a field stop 16. A reflected light beam generated by reflection is branched. Aperture stops 24A and 24B for focus adjustments in which an approximately rhombic opening 26 is formed are each arranged on the optical paths of branched reflected light beams. The quantity of light of each reflected light beam which has passed through the approximately rhombic opening 26 is detected at optical receivers 28A and 28B for focus adjustments. A focusing device 36 controls the position of the mounting part 12 on the basis of the difference between detected quantities of light.
