摘要
为了满足紫外告警系统在**方面的应用,采用二元衍射元件和非球面元件,设计了一种日盲紫外告警的光学系统,其工作波长范围为240nm~280nm,视场角为40°,采用“负-正”型式的反摄远镜头结构,仅由5块透镜构成,此镜头结构简单、体积较小、能量集中度高。结果表明,此设计方案能很好地解决紫外镜头轴外像差校正的问题,使点列图能量集中,小于紫外CCD的像素,满足紫外告警设计要求。
Abstract
In order to meet the application of the ultraviolet(UV) warning systems in military domain, an optical system of a solar-blind ultraviolet warning system was designed with binary diffractive elements and aspherical elements. Its working wavelength is 240nm~280nm, full field of view is 40°. It is composed only of five lenses with “negative-positive” reverted-telephoto type. The lens has simple structure, small size, and high energy concentration. The results show that this design is a good solution to the UV-axis lens aberration correction, the spot is less than pixel size of UV-CCD, making point diagram with high energy concentration, and satisfying the design requirement of UV warning systems.
