Abstract
A chromatic confocal sensor configured for calibrating an orientation of an equipment about the optical axis of the chromatic confocal sensor, wherein the equipment is disposed at a first orientation about the optical axis of the chromatic confocal sensor, the chromatic confocal sensor including a light source, a collimator, a lens and a reticle, wherein the light source, the collimator and the lens are coaxially disposed along the optical axis, the reticle is configured to be interposable between the collimator and the lens along the optical axis, an image is configured to be cast by the light source through the collimator, the reticle and the lens on the equipment, the image is disposed at a second orientation about the optical axis and the equipment is calibratable by aligning the equipment with the image such that the first orientation approaches the second orientation.
