Tolerance analysis of lenses with high zoom ratio

Chir-Weei Chang; Gung-Hsuan Ho; Chy-Lin Wang; Wei-Chung Chao; John D. Griffith

Axial and lateral compensators are used for zoom systems tolerancing to improve the manufacturability of high zoom ratio lenses. An investigation into the tolerance distribution for various zoom ratios, and compensation conditions and corresponding performance is presented. A flexible method is applied to a rear focusing four-groups 10X zoom to demonstrate the effectiveness of different compensators.
