Abstract:
A calibrator used for a non-destructive transmission optical measuring apparatus for quantitatively determining a specific component contained in a measuring object by making light incident on the measuring object at its light-incident area, detecting the light having entered, and having been transmitted through, an interior of the measuring object, at its light-emergent area set at a position different from the light-incident area, and measuring absorption of the light to quantitatively determine the specific component contained in the measuring object; the calibrator comprising;a closed body having a light inlet and a light outlet, an interior of which is provided with a substance having light absorption characteristics identical or similar to those of the specific component, and in which a light path length from the light inlet to the light outlet is so set as to be equal or substantially equal to an effective light path length of the light transmitted through the interior of the measuring object.
