Abstract
The properties of optical system will be decreased by the centering errors of the lens. But the centering errors are inescapability during the manufacturing process. Different from the sphere surface, the aspheric surface is a center axis only, the centering error has been fixed once the two surfaces are polished or turned et al. For high precision optical system assembly, the centering error of the aspheric lens must be measured accurately. The principle of centering error measurement for aspheric lens is introduced in the paper. The device for the centering error testing has been developed. For a high accurate measurement, the factors include axis the tilt and shift of axis of Z, F, T and the coincidence error e of symmetry axis of aspheric surface and reference axis are analyzed. Finally, a double aspheric surface lens is tested by device self developed and TRIOPTICS AMT100 with the same method and the results are almost agreement.
