PROBLEM TO BE SOLVED: To correct a change in the quantity of light and/or the illuminance distribution caused by a change in the setting position of an object in an apparatus which images the object by illuminating the object set in a dark box with light. SOLUTION: The setting position of a sample 100 is detected by a position sensor 20. A bundle optical fiber 50 is moved by a position control unit 70 on the basis of the setting position of the sample 100 along a linear rail set to a corner of the dark box 10 to which the optical fiber 50 is inserted, so that distance between an emitting part of the optical fiber 50 as a vertical light source and the setting position of the sample 100 becomes a fixed distance. |
