Disclosed are in-line apparatuses, systems and methods for measuring a physical characteristic of a constant supply of an ophthalmic device, the apparatuses including: an interferometer; an automatic alignment system that positions the interferometer or ophthalmic device; and a central processing unit in communication with the automatic alignment system and receiving measurements from the interferometer. The in-line apparatus measures the desired physical dimensions of the ophthalmic device in real time. In-line systems, apparatuses and methods for measuring a physical characteristic of an ophthalmic device can include: a camera imaging an actual position of a feature of the ophthalmic device; a vibration resistant interferometer projecting a surface measurement beam having a wavelength that transmits through a beam splitter onto the ophthalmic device; and an automatic alignment system positioning the interferometer and the camera.
