A rangefinder, comprising a housing (1), an emission mechanism (4) and a receiving mechanism (5). The emission mechanism (4) and the receiving mechanism (5) are arranged on the housing (1), and the emission mechanism (4) is provided with an emission channel (42). The rangefinder also comprises a translucent blocking piece (7) arranged at a front portion of the emission channel (42) and located within the housing (1), the blocking piece (7) being arranged at a certain angle of inclination with respect to an emission direction. The rangefinder has a simple structure, the translucent blocking piece (7) is arranged at the certain angle of inclination with respect to the emission direction so as to prevent reflected light and stray light from being directly reflected onto a receiving assembly, and measurement accuracy is significantly increased. |
