Abstract:
A distance meter telescope having a telescope lens, a laser receiver, a display unit, a laser emission module, a beam splitter assembly and an eyepiece; the laser receiver receives a laser beam emitted from the laser emission module; the beam splitter assembly has a roof prism, a prism separation board, a first semi-penta prism and a second semi-penta prism; the roof prism has a light input surface, a roof surface, and an output surface; the first semi-penta prism has a first entering and reflective surface for output light, a first input and output surface and a first gluing surface; the second semi-penta prism has a second entering and reflective surface for output light, a second input and output surface and a second gluing surface. The beam splitter assembly makes the light beam passing through the telescope lens, the laser light beam received by the laser receiver and the light beam from the display unit coaxial. Accordingly, product size can be reduced and the prisms can be shared.
