Abstract
A scanner includes laser stimulating ray sources, a motor for an objective lens incorporated in a confocal optical system and a controller adapted to produce position data by placing a sample carrier in which five distance measuring devices are set on a sample stage, and measuring a distance between the objective lens and a reference position on the distance measuring devices and a distance between the objective lens and measurement positions on the distance measuring devices, to produce focus position data produced by setting a luminescent material included in a focus position determination device at the reference position, scanning the focus position determination device with the laser beam, detecting fluorescence emission, and changing the position of the objective lens with a predetermined pitch, and to cause the motor to adjust the position of the objective lens based on the focus position data corrected with the position data.
