Abstract
Designed to be fitted to an ophthalmic lens grinding machine to be calibrated instead of an ophthalmic lens, a calibration template is in the general form of a disk with a circular contour over at least part of its perimeter. Its contour forms two localized angular points circumscribed by a common circumference and having a relative angular offset.
