变焦系统中,动组间相对位置的变化会导致各镜组的初级像差特性发生变化,环境温度的变化还会导致各焦距位置热差的改变,给无热化连续变焦系统的设计造成较大困难。针对该问题,从光学系统像差模型出发,将变焦系统像差分为定组像差、动组内像差和动组间像差三类,并结合变焦系统的消色差和消热差模型,讨论了无热化连续变焦光学系统的设计原则,及变焦系统设计中各组元的光焦度分配和材料选用方法,给出了一个宽波段连续变焦光学系统设计实例,该系统F数为5、焦距范围为8~120 mm、焦面对角线长6.2 mm、波长范围为0.48~0.68 μm和0.7~0.9 μm。所述系统仅采用了七种普通光学玻璃材料,透镜总数12组16片,总长仅90 mm,在-40~60 ℃范围内,变焦全程均具有较好的成像质量和公差特性。 |

The primary aberration of each lens group will be changed with their movement, and the change of environment temperature will also lead to defocus, both of which will cause a lot of difficulties in the zoom lens design process.To solve this problem, aberration functions do depend and not depend on group movement were introduced based on optical aberration theory, and lens power distribution and material selection method were discussed with the achromatic and athermal design model futher.A visible-near infrared (Vis-Nir) optical system under the requirements of F/5, focal length of 8-120 mm, focal plane diameter of 6.2 mm, work waveband of 0.48-0.68 μm and 0.7-0.9 μm was designed with mechanically compensated method and optical passive athermal technology.The proposed zoom lens system, which used 7 kinds of common optical glass, consists of 12 groups 16 lenses, total length of only 90 mm, has good image quality and tolerance character among the zoom range within -40~60 ℃. |
