摘要
连续变倍照摄像物镜在各种照相和摄像等领域有着广泛且必不可少的实际应用.通过大量反复研究与计算,在参考他人资料的基础上,设计出了可用于像方线视场16 mm的照摄像机物镜,变焦范围为15～150 mm连续变倍,物镜的像方F数为2.5,MTF曲线在50 lp/mm时值均大于0.12,畸变在8％以内,是一成像质量满足实际要求的连续变倍物镜.
Continuous zoom technology is essential and widely used in all kinds of photography.Based on repeated research and computation,as well as other related data,a new design is proposed that can be used in cameras with 16 mm image vision field.The design can still bring about zoom lens with zoom range of 15～150 mm,objective lens with image vision F number of 2.5 and under 50 lp/mm,the mean value of MTF curve above 0.12 and the distortion below 8％.It can be predicted that the designed zoom lens will meet actual requirement.
