本目镜采用国际标准设计，目镜连接管直径为23mm,特别是可安装直径为21mm或19mm的玻璃分划板，可通过调节视度进行聚焦，形成清晰锐利的图象，而定焦目镜则无此功能，分划板位于螺纹档圈位置。对于凯涅尔目镜和广角目镜，可从目镜底部安装分划板。而对于Periplan目镜，由于光学设计不同，在安装分划板时需先拆除底部，将分划板装于接眼镜和场镜之间。本广角设计合并了接目镜和场镜目镜上端的的调整位置，设计较为复杂，可进行精确对焦，因此图象质量好。本系列所有产品为DIN形式。

DIN format: magnification of eyepiece determined using a 160mm tube length. Based on the German standard.
