该仪器由北京光学仪器厂制成。它带有潜望及测角装置,同时实现观察定向、测距和测方位。适用于地面炮兵及地质、矿山、邮电、港务等测量工作。测距仪由主机、电源箱和三脚架组成。主机由观察、测角和测距三系统组成。观察系统是带潜望的双筒望远镜。测角系统包括测高低角和水平角两套机构。主机可绕竖轴和水平轴自由转动,角度值由指示窗和读数鼓轮读得。测距系统有发射和接收两部分。光路中用了一种多层介质膜镜片,发射、接
The instrument made by the Beijing Optical Instrument Factory. It is with periscope and angle measuring device, while achieving observation orientation, ranging and measuring position. For ground artillery and geology, mining, post and telecommunications, port and other measurement work. Range finder by the host, the power box and tripod components. Host by the observation, angle measurement and ranging three systems. The observation system is binocular with periscope. The goniometry system consists of two mechanisms of altimeter low angle and horizontal angle. The host can rotate freely about the vertical axis and the horizontal axis. The angle value is read by the indicator window and the reading drum. Ranging system has two parts to launch and receive. Light path with a multi-layer dielectric film lenses, launch, then
