Method for measuring thickness of center of centered and non-centered lens, involves pivoting buttons so that button axis falls together with bearing rotation axis, and measuring thickness of lens on rotation axis by contacting of buttons

摘要

The method involves aligning a lens (100) on a rotary bearing (102) such that a variable of radius of an impact circle of a laser beam visualized on a display is minimized, where an optical axis (104) of the lens falls together with a rotation axis (106) of the rotary bearing. Push-buttons are arranged in an opposite direction in an aligned manner and pivoted such that an axis of the push- buttons falls together with the rotation axis of the bearing after pivoting. Thickness of the lens on the rotation axis is measured by contacting of the push-buttons. An independent claim is also included for a device for measuring the thickness of a center of a centered and non-centered lens.
