Abstract
According to examples, a system for determining a ROC of a DUT may include an illumination source to output a light beam, an imager to capture images, and optical components positioned in an illumination path from the illumination source to a DUT location and in an imaging path from the DUT location to the imager, in which at least one of the optical components includes a fiducial mark. The system may also include a controller to cause a relative position between the DUT location and a lens in the optical components to vary and cause conjugate images of the fiducial mark to be relayed through the optical components to the imager and determine the ROC of the DUT based on an application of a correlation of ROC-dependent optical conjugate positions in the optical components induced by the ROC of the DUT.
