Abstract
A calibration tool for a scanning endoscope includes: an abutment portion that is in contact with and abuts an illumination window provided in a distal end face of an insertion portion of a scanning endoscope and is configured to be in contact with a region of the illumination window other than a region in which an illuminating light beam applied from the illumination window is scanned; and a chart with a calibration pattern drawn thereon, the calibration pattern being provided for calibrating a scan pattern of the illuminating light, the chart being arranged parallel to the distal end face with a predetermined distance from a surface of the illumination window positioned as a result of the illumination window coming into contact with the abutment portion, according to a size of the calibration pattern, whereby image calibration of the scanning endoscope can accurately be performed with a simple configuration.
