Lens module Eccentricity Tester (LensCT-AF) is a serial high precision, non-contact optic-centration testing equipment. They are equipped with a precision air bearing, and specially designed for Mutli-Lenses group or with large aperture lenses. The friendly software can directly record the data and show the testing result in required way, and make the actual measurement simply and efficiency. They could be used for single lens inspection before module assembly, or center offset control during the lenses assembly, also the combination center deviation detection after module assembly, as well as the every curve surfaces eccentricity reveal for each component lens inside the module after assembly
