ABSTRACT
The objective of this study was to present a high-speed, on-line means of measuring interior tilt and decentration in a singlet lens. We propose a noncontact method based on polarized optics, which provides inspection functions for the practical measurement of lenses. The proposed system was used to measure a tilted and decentered lens, and the results of which showed strong agreement with those obtained in theoretical predictions and CodeV simulations. The proposed method provides a wide field of inspection applicable to lenses with a diameter up to 70 mm. Measurement accuracy is of 0.14 deg/pixel in tilt, and 33 µm/pixel in decentration. Inspection time is only 0.78 s.
