The laser ranging telescope is an instrument which can accurately range the target by utilizing laser and can also remotely observe the target. The distance measurement principle is to calculate the distance between the observer and the target by emitting a thin laser beam to the target and measuring the time from the emission to the reflection of the laser beam by the target, and the remote observation principle is to receive the light reflected by the object through the objective lens and then display the object received by the objective lens through a display screen arranged at the front end of the eyepiece.

In the observation process, the operator directly observes the display content of the built-in screen, so that the diopters corresponding to the display content are different when different people use the display content. Therefore, it is necessary to obtain a clear image by adjusting the distance between the lens and the display screen so as to obtain a proper diopter. However, the existing laser ranging telescope adopts manual rotation focusing for focusing the ocular lens, so that when the laser ranging telescope is used, two hands are required to operate, and inconvenience is brought to observation.
