2、Properties：

（1）It is a binocular observation instrument, which is used to observe, search and monitor distant objects during the day; The mirror is equipped with advanced curve division, which can directly measure the direction Angle, height Angle and distance of the target.

（2）The optical lens adopts comprehensive precision multi-layer coating, the transmittance is up to 82.3%, and the imaging is sharp, which makes it obviously superior to similar telescopes at home and abroad in observing brightness, image quality and the authenticity of object image color.

（3）Mirror body adopts all-metal structure, strong and durable; Rubber armoring, shock-absorbing, skidproof design, strong ability to withstand turbulence and vibration, can withstand more than 20 gravity acceleration impact, fully adapt to field environment.

（4）The structure adopts componentized design and has good general maintenance performance.

（5）The mirror body is protected by high-purity flushing nitrogen. It has passed the 6-level waterproof, dustproof, fog-proof, rain-proof, shock and drop test, and fully meets the requirements of mil-std-810, which can be used all day.

（6）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).

（7）The operating temperature range is -43℃~+55℃, which can meet the needs of all-weather operations in different geographical zones.

3、Using range：

Field operation, electric power, telecommunications, public security, armed police, border guards and other units use.
