、Technical parameters：

2、Properties：

（1）Multi-layer coating, sharp imaging, in the observation of brightness, image quality and the authenticity of image color and other aspects is obviously better than similar telescopes at home and abroad.

（2）With wide field of vision, large diameter of exit pupil and long distance of exit pupil. It can observe the target clearly and comfortably in low illumination environment like dusk and dawn and wear gas mask (or glasses).

（3）Professional waterproof eyepiece, high sealing performance, can well meet the needs of all-weather operations.

（4）Operating temperature range -40℃ - +80℃, can withstand the harsh high and low temperature environment, can well meet the needs of all-weather operations in theater of different geographical locationss.

（5）The whole metal structure of the mirror body is durable. Cadmium sulfide armoring, shock-absorbing and skidproof design, has strong ability to withstand turbulence and vibration, can withstand the impact of more than 20 gravity acceleration, fully adapt to field environment.

（6）With partition inside the mirror, it can roughly measure the distance and azimuth of the target.

（7）Adopting componentized design, it has good general maintenance performance.
