Scanning Laser Range Finder AR861 Specifications as below for you:
 

Laser range finder is a tool to measure the accurate distance to the goal by utilizing laser. While working, laser range finder projects bunch of very thin lasers to the goal, the photoelectric element receive goal reflection''''s laser beam, the timer determination laser beam receive time from the launch, calculates the distance from the observer to the goal.

Laser finder weight is light, the volume is small, simply operation, quickly and accurate, its error is only other range finder''s 1/5 to1%. Thus it is widely used in the topographic measure, battlefield measure, tank, airplane, naval vessel and artillery to goal range, and measure the height of cloud layer, airplane, missile as well as satellite and so on. It is an important technical tool to enhance the tank, the airplane, the naval vessel and the artillery precision.
