| 摘 要： | 设计了一个用于远距离监视电视的折反射式步进变焦距透镜。为使微光、白光和近红外三个波段共用一个光学系统，提出一次成像折反射式变焦，并进行了理论分析和给出了设计实例。克服了二次成像折反射式步进变焦方式二级光谱不能校正的缺陷，并且杜绝了像面中心产生黑斑的可能，结构也比较简单。

| Abstract: | A catadioptric step zoom lens for remote supervision TV is designed. Once imaging catadioptric step zoom is proposed so that three bands such as weak light,white light and near infrared share the same optical system. Theory is explained in detail and design examples are displayed in the paper. The disadvantages that the secondary spectrum of reimaging catadioptric step zoom lens can not be corrected are overcome. Moreover,the black spots generated in image plane center are avoided and the structure is simpl... |
