摘 要:为了满足汽车倒车需求,设计了一款结构简单、生产成本低廉的广角倒车镜头。镜头为4片式结构,第1片为玻璃,其余3片为塑料,使镜头满足在恶劣环境下工作的要求。镜头F数为2.8,水平视场为185°,且实验结果显示边缘视场畸变得到较好控制。设计的镜头已经开始量产。
In order to meet the needs of the backing-up lens in cars, a wide-angle lens has been designed. The lens has four elements, the first is a piece of optical glass, the other 3 elements are plastic, and the lens is able to work under bad conditions. The lens has an F number of 2.8, the horizontal field is 185 degrees, and the test showes that the off-axial distortion is corrected perfectly. Mass production of the lens has begun.
