16X精密变焦镜头是个高品质模组视频镜头，分辨率高，景深大，用途广，放大倍率从0.063X到190X，工作距离可从370mm到13mm..
整个光学系统需要以下器件：C接口适配器，Dovetail管，前变焦组，后变焦组，物镜（MITUTOYO 适配器），40”光纤束等。光纤适配器可连接照明器件，安装方法可参见316页。可选环形光连接口(#56-215)和环形导光设备.
锲形管可调焦以保证等焦面。SENSOR最大尺寸为1 /3” 可配０.５Ｘ的套管，SENSOR最大尺寸为2/3”可配1.0X的锲形管。０.５Ｘ的调焦管不能与Mitutoyo物镜兼容，使用同轴照明以及２／３”SENSOR可以降低远场校正变焦范围，同时变焦范围也 有所降低
