The utility model discloses a
monocular telescopic
laser range finder with a novel focusing function, which comprises a telescopic optical
system, and the telescopic optical
system comprises an objective lens group, an inner focusing lens, a
beam splitter prism group, an LCD (
Liquid Crystal Display) and an
eyepiece group which are sequentially arranged along an
optical axis L from a scene side to an eye side, the objective lens group, the inner focusing lens, the
beam splitter prism group, the LCD and the
eyepiece group are installed in a shell, the
eyepiece group can move left and right along an
optical axis L so as to adjust the distance between the eyepiece group and the LCD, people with different eyesight can clearly watch images displayed on the LCD, the inner focusing lens is additionally arranged between the objective lens group and the
beam splitter prism group, and the lens group can be used for adjusting the distance between the eyepiece group and the LCD. The inner focusing lens can move left and right along the
optical axis L so that sceneries at different distances can be imaged on the LCD, the inner focusing lens is driven by the driving mechanism, two functions of adjusting the distance between the eyepiece group and the LCD and focusing and imaging the sceneries at different distances on the LCD are realized by adopting two sets of independent mechanisms, the two functions do not interfere with each other, and the implementation is easy.
