全塑料3倍全动型变焦镜头设计
Design of 3×plastic zoom lens with all-movable components
摘要
Abstract
To address the increasing demand for compact,high-performance zoom lenses in consumer electronics,this paper presents the design of an all-plastic 3×continuous zoom lens featuring fully mov-able components.An all-movable zoom structure is employed,wherein all lens groups are mobile to opti-mize both zoom range and image quality.Q-type aspheres are utilized to enhance optical performance,while plastic materials serve to reduce manufacturing costs.Optical properties are assigned to each surface using LightTools,and ghost image analysis is performed via ray tracing.The optimized lens achieves a 3×zoom range from 22.72 mm to 68.16 mm with an F-number of 4.5 and a total optical length under 68 mm.At object distances of 10,1,and 0.2 m,the diffraction MTF exceeds 0.3 at 80 lp/mm and 0.22 at 160 lp/mm across all fields of view at various zoom positions,ensuring high-resolution imaging.The cam curve is smooth and free of inflection points.Ghost image analysis indicates that the peak irradiance of ghost images formed by all surface combinations remains below 0.012 2％of the main image's peak irradi-ance,demonstrating negligible impact on system performance.The proposed all-plastic 3× all-movable zoom lens exhibits excellent optical performance,compactness,and manufacturability,offering a valuable technical reference for the design of high-performance,miniaturized zoom lenses.关键词
