Abstract
A diagnostic apparatus includes a measurement head, a translating calibration element, and a calibration element actuator. The measurement head includes a diagnostic light source, a light sensor, and a measurement head body. The diagnostic light source operates at a diagnostic wavelength λand the measurement head body supports the diagnostic light source and the light sensor in a spaced apart relationship across a target fluid passageway to define a diagnostic light path extending from the diagnostic light source to the light sensor. The translating calibration element is partially transparent to light at the diagnostic wavelength λand the calibration element actuator is structurally configured to move the translating calibration element into and out of the target fluid passageway. A size and geometry of the translating calibration element is such that the translating calibration element occupies a substantial entirety of the diagnostic light path when moved into the target fluid passageway.
