摘要： PROBLEM TO BE SOLVED: To resolve inconvenience caused by dispersion of light guides or light source lamps by calculating/displaying a light quantity correcting factor by comparing the set light quantity of an initial light source device with a measured light quantity, and correcting the light quantity to the initial set light quantity based on the light quantity correcting factor. SOLUTION: A set light quantity storage means for storing the initial set light quantity of a light source device is installed in an outer controller 1, and the initial set light quantity is memorized there. When a light guide 2 or a light source lamp is replaced by another one, since the light quantity is made different from the initial light quantity, the light quantity is re-measured with the outer controller 1, and the deviation of the light quantity is corrected to the initial set light quantity. When the measurement of light quantity is finished, the initial set light quantity stored is compared with measured light quantity, a light quantity correcting factor is calculated to make the light quantity same as the initial set light quantity and displayed on a display 10.
