Abrégé

A beam splitting system for laser ranging includes a roof half-pentaprism, an isosceles prism and a compensating prism. Due to different compensating prisms, there are four light splitting combinations in total. Light of a certain wavelength is incident from one side of the roof half-pentaprism, and is reflected therein for several times and finally emergent into the isosceles prism where it is reflected for several times and finally emergent in a direction consistent with an incident light axis. Light of another wavelength is incident from one side of the compensating prism, and finally emergent from one side of the roof half-pentaprism or one side of the isosceles prism. Different light splitting ways may be caused due to different positions of both prisms and data LCDs. A number of different optical ranging systems will be provided if a laser rangefinder employs different light splitting combinations.
